First let me say that I know how the bonuses are calculated.

For health reductions I have 7 faction bonuses and a grim Aries. When I first got the unit my health regain went from -30% to -34%. Yesterday I noticed that it is now -33%. So I was wondering what changed in the calculation and has anyone else noticed this small change?

The 1% is not making or breaking me so I'm just looking for an explanation as to why this was lowered.
