Well it is a mute point now as I have already agreed with @tetrasodium that subtract 1 or 2 damage from a PCs damage is very minor operation and not affecting the time. I was not thinking about the issue properly. However,...
Interesting, I had never thought of doing it that way before. Have you thought about why you do it that way?
That is an odd statement (bold red). You clearly added a step in the DR example (you subtracted 2 from 5 before writing down 3 damage). I agree the time it takes to do that is not relevant in the game, but it is clearly an additional step (a purely mental one, but still an additional step). Why do you think it is not an additional step?
I'm not 100% sure why I do it that way.
Somewhere along the line, it just made more sense to me. I can barely remember not doing it that way.
When I started to play games in which different HP thresholds mattered (D&D 4th Edition with Bloodied; GURPS with tangible effects tied to HP loss,) I would make note of what those thresholds were (i.e 1/3 HP = N) and it still made sense. "Is my damage total more than this number? No? I'm good. Yes? I'm injured/dead/whatever."
As for the steps, I was comparing [HP - damage] to [Damage - DR]. To me, that's the same.
I suppose visually looking at two numbers to see if one is higher or lower is also a step, but I don't see that as being very difficult.
