Oh, and yea, when I write something like "Base Health from 8,000/20,000/36,000/60,000/65,000 => 9,000*mk.", the first set of numbers is the CURRENT value. So reading that and complaining about 8000 health for a mkI is nonsensical
You should be complaining about 9000 health for a mkI!
More seriously, the reason I include both the old and new values is so you can see the proportions of the changes rather than just the absolute values, because the absolute values I'm working on (and using in the release notes) are not easily translated into the effective values you actually see in the game.
Put another way, mkI bomber health was increased by about 12.5%, mkII was reduced by about 10%, mkIII is staying exactly the same, mkIV was reduced by about 25%, mkV was reduced by something like 18%.
