I don't think your comments were held, otherwise I'd be able to see them. Might just be Youtube being Youtube.
I think it's entirely possible that I made the heal penalty not matter by making the powerup strength a bit higher. I have no clue how any of that works, but if you were to take Deimos-1 and use a medikit while moving around you'd definitely notice it doesn't heal as much.
Instead of 25 HP, you'd get 20 or 15 back. The penalty is just that the whole regeneration thing doesn't have time to go all through, really.
