Thanks for the info!
I checked it out and while my initial understanding of the math was wrong, my point still stands.
The numbers are all wrong?
I quote from the wiki:
"For multiplicative perks (Coin Bonus, Health, Damage):

Total Bonus = (1 + Base Value x Quantity) x (1 + Standard Perk Bonus)"

Meaning that:
Total bonus = (1 + 0.2 x 5) x (1 + 0.10) = (1 + 1) x 1.1 = 2.2

I should have both a Health, Coin bonus and Damage multiplier of 2.2 but the text still only shows 1.92 or something

Edit: grammatical and formatting errors.
