Efficient or Escapist?

With 300 pushups under my belt today and thirty minutes left before midnight (not that I'm afraid my bicycle will turn into a pumpkin if I'm not tucked in - though I'll hit the sack right now if it means my pregnant wife will morph into Cinderella) I decided I wanted to do 100 more. This led me to my quandary of the moment: do I try to do them in three sets or four?

What's the big deal, you ask? Maybe nothing, but here's what I'm wondering.

So far I've been doing sets of 30. Right now, after 300 on the day, cranking out thirty at a time starts getting tough, particularly for those last 5 reps, which, if completed, are as much of a workout as the first 25 when your muscles still have some twitch in them.

Doing four sets of 25 will likely be much easier than two 33's and a 34 or whatever. And there's my conundrum of conscience. Do I serve myself a little extra punishment or just get those last 100 out of the way and chalk them up? Is the goal just a number or should this endeavor aim to incorporate more rather than less physical effort? And what does my answer mean as it relates to the inescapable inquiry into the soul that this whole stupid idea will ultimately comprise?

Ah, screw it, I'll do what I can until my shoulder tells me to go find my glass slipper.
