Injury Barrack?

so theres no info on the injury barrack on the wiki

i was wondering at what lvls the percentage breaks?

1-4 heals 10% of dead soldiers then at lvl 5 theres a break to 15%
when is the next break? my injury barrack is currently lvl 10 and the button info for lvl 11 doesn't foresee another break.

i have a an injury barrack too.
it seems like it will only be 10 forever

Full information on the Injury Barrack is in the official documentation, under Construction, which can be accessed by clicking the Support button at the bottom of your game screen.

The Injury Barrack increases in increments of 5% at level 1 (10%), 5 (15%), 16 (20%), 26 (25%), and 30 (30%). Level 30 is the maximum you can improve this structure.
