I noticed when comparing my army camp production, using the Army Camp Boost artifact and the Ad Bonus towards Army Camp Production, a discrepancy. Currently, with the advancements, I have a boost of +190%. My Army Camp Boost artifact gives me +40% army production, and watching the ad gives me +30% army production.
Where I get confused, is when I compared the production using the artifact and no ad boost(+230%), and using the ad boost and no artifact(+220%). When my total bonus is equal to +230%, my two army camps combined produce 9.36K armies/sec (5.32K + 4.04K). However, when my total bonus is equal to 220%, the same two camps at the same upgrade levels produce 10.69K combined (6.08K + 4.61K).
I have screenshots to confirm I read this correctly, and I’m just confused how a bigger total bonus yields significantly less armies/sec compared to the smaller total bonus. I Have the statistics advancement to confirm the total bonuses, so I’m not sure how I could be reading this incorrectly.
Obviously using both is optimal, but this has been bugging me for a little while. I’ve been playing Floating Rocks for the last month to record the cost, and increase in armies/sec and ore/sec for all of the upgrades, in an attempt to see at what rate these increase. If these rates are inconsistent between levels, then this is a waste of time, but I enjoy this kind of stuff. Any help would be appreciated

The modifiers pop-up is incorrect. The 30% ad boost is multiplied, not added.

With the artifact and techs, it's +230%.
With the artifact, techs, and ad bonus, it's 230%*1.3 + 30%, or +329%.

Thank you very much, this answers my question perfectly
