I don't follow. Maybe an example would help ... what equation would I use to estimate the next few draft sizes under conditions of:

- 2 hrs since last draft
- last draft was at a minimum (pool was depleted)
- earned 4T armies so far on current level
- just bought 350B mercs & received 25B armies from a cache

I drafted over and over every 6 minutes for an hour with different draft modifiers on different levels. I did a linear regression on the minimum draft sizes (as a multiple of army income) to get an equation of the form y = ax + b. Part of b comes from the fixed portion so I removed that piece by subtracting a from b. I divide by 360 because it's the time between drafts.

I then solved the equation:
(b-a) / 360 seconds = sliding / (1 - sliding)

(169.5769 - 106.3462) / (360 Seconds) = sliding / (1- sliding)

It comes out to 14.94%

I only solved the maximum draft equation and minimum draft equation for fixed armies per second.

Some of the final maps have total armies of 4-7T, so 15% of that would be 600-900B, but I've never seen anything that high. After buying even as high as 350B mercs, the drafts following are in the range of (going from memory) 2-6B, which assuming I was 50-75% finished the map (# of armies) at that point would make the value <1%.

To clarify, as far as I understand the situation so far, the 15% DOES NOT apply to one individual draft. You will never have a single draft that is the size of 15% (or whatever percentage) of your total armies earned. What the percentage is saying is, that the game tries to get the number of overall drafted armies as close as possible to 15% of the total armies earned. If you have the Level 1 Statistics, look at the numbers when hovering the current army count. The mentioned percentage is the ratio between "Total armies from drafting" and "Total armies earned". Whether 15% is in fact the correct number here, we haven't finally determined.

Regarding the 15%: Wasn't the idea that regardless of the individual draft, the fact that my drafts vary means that I haven't depleted the sliding portion? So, I use an uncommon Draft Boost artifact but I don't draft every whatever minutes they appear. Hence, my drafts are not the same but varying. Therefore, I haven't depleted my sliding portion, hence, I should still be below whatever percentage.

If I haven't made a logical error here, I doubt the 15%.
In my current level I earned 7.0942B armies. 15% of that would be 1.06413B. But I already drafted 1.2836B armies.

As I said, I'm quite sure that I should (always) be below the percentage that the sliding portion targets. But I have drafted more than 15% of the total armies. Hence, the percentage would have to be higher than that, at least 18.09% based on my current numbers.

The Fixed Draft is not affected by the Cap.

So, of that 1.28B total drafts, 1.06B is Sliding and 0.22B is Fixed.

The more often you Draft, the bigger the Fixed amount will be. Increased Draft Size increases the Fixed amount, but the Sliding Cap stays in place.

Then we have a totally different understanding of what the percentage exactly controls. Because, yeah, sure, you could divide the actual draft into two pods. But that doesn't change the fact that as long as the total draft is lower than the total overall, there should be a sliding portion, if you exceed the percentage, the sliding portion should be zero. At least this is how I interpreted Fizzer's statements.

So, of that 1.28B total drafts, 1.06B is Sliding and 0.22B is Fixed.

After all, both numbers combined make my "total drafts". And only my "total drafts" are compared to my "total overall". Not some magical portion of my drafts.

Can someone put this like Im a 2nd grader.

Is draft boost artifact worth it or not? I swap it in everytime i collect but if its not making any significant difference Ill consume it and move on.

tl;dr

If you Draft constantly, YES.

If you Draft infrequently, mildly useful.

If you draft every 6 minutes with no modifiers, your fixed drafts will be roughly equal to 1/4 of the amount gained from army camps. With an 8% Draft Boost, that means your fixed drafts will go from 25% what your camps give to 27% what your camps give.

Divide your draft modifier by 4 to see the percentage effect it will have in comparison to armies from camps, if you draft constantly.

The overall effect will be slightly higher because you'll get a few more armies from the sliding portion, but this is a good rule of thumb.

@Mr Perfect
I also give up understand the proposed math ... BUT ... both the artifact & AP Adv are confirmed to increase the resultant amount, so Yes, it's worth it, and imho, it doesn't depend on how much you draft, but is especially beneficial if you buy lots of mercs as this gives a massive boost to it and gives you large drafts for a number of drafts.

Here some folks are saying that Drafts can be as large as 25% of your total armies earned from camps ... don't listen to that. LOL. Seriously, I upgraded AP Adv Increased Draft Size to 250% a long while back, and my draft sizes are ALWAYS more than my armies earned from camps -- and I have a SuperCamp, so that's even compared to an inflated army camp income. I also have +150% Army Camp Production AP Adv as well. I also use the Epic Draft Boots (+32%).

Of all army earning counts displayed at the end of levels, those provided by army camps are always my lowest figure. Order is typically: (lowest to highest) army camps, drafts, caches, hospitals, mercs. Sometimes the order of drafts/caches and hospitals/mercs change orders, but of the order AC, D, C, H, M, the D/C are always in the middle, and the H/M are always on the high end, AC always on the low end. I also have +45% additional mercs AP Adv. Lately I added +50% merc discount so that gives me both cheaper and more plentiful mercs, and this is turn will drive up the Drafts again.

Krinid, I was referring to fixed drafts only when mentioning the 25%. Total drafts usually exceed armies from camps for me as well (0% draft boost). Fixed drafts alone don't account for very much of that total.

Hi,
Im on finishing level now and take many mercenary.
so i watched the draft sizes. if dont equip the draft artifact ( uncommon 8%) i draft 603m armies .
If i equip it i just get 533m armies.
anyone has an idea whats going wrong here?
current armie income is 137.5k
and i have no advancements

I've done the same many times ... what's happening is you're mostly but not completely depleting the sliding portion of the Draft size while NOT equipping the artifact to get 603M, then equipping it afterward with a smaller sliding portion remaining to get the 533M Draft.

Try it the other way around, if you equip first and then unequip second, and if you get a Lower/Higher Draft, then screenshot it and bring it back here. Though I guess you'll only have the screenshot of the 2nd Draft at that point so it wouldn't have meaning. Anyhow, it **should never happen.

**Stuff that should never happen has in fact happened. Nothing is ever certain, especially in cases like this where you can't really test it to know what your exact values with and without artifact would be.

2nd pic is a bit bad but its 609m


as i tested it several times.I can cause if collected so many mercenary

Edited 6/8/2021 17:54:52

609M is without artifact? 533M is with?

If so ... are you by chance swapping out ACB in order to swap in DB?

u see what is equiped down right side
but i just equip it for the draft. afterwards i change to army camp boost.
anyway cant be its less ???

Edited 6/8/2021 18:01:28

Did you buy any Mercenaries or conquer any Caches between Drafts? That will affect how much you receive. So will time between Drafts. A small sample size with little data is impossible to generate conclusions.

Oh, didn't even notice. ACB will DEFINITELY affect your Drafts. Your CURRENT income affects Draft size, so it must be equipped.

Edited 6/8/2021 18:05:35

Oh yea I missed the pic of the artifacts, so yes, you're swapping out ACB to swap in DB. So instead do this, swap out TMB to swap in DB, leave ACB in, and do the same thing, and it should be higher with the DB artifact equipped.

ACB boosts armies/sec which boosts drafts. Use them both for best drafts.

i buyed several billions think an hour ago. and still drafting now the " benefit" of it. but i tested this several times same result with artifact equipped. ( just for the draft so 10sec) 533m . without its 609m.
is it neccesary to have euipped the draft artifact the hole time to get a benefit of it?

Edited 6/8/2021 18:10:32

No, just don't unequip ACB. You need ACB+DB both together.
