Not that there's anything wrong with doing that ^^^....but it's really no different than comping.
.
Oh look... miro wants to argue...
So I'll start playing something and hopefully get all the way through. If I don't I'll decide, based on how long the song is, how difficult it is to play, whether there are breaks in it, and how far I got whether I ditch it and start again, or try a punch in from a point and continue to the end. Usually, it's simpler just to go back to the start, but I'm not just chugging chords here most times, so I'm open minded on it, particularly if it's a bit complex. At the end, I have a single complete track.
What I don't do is do multiple complete takes and then listen through them and decide that verse 1 from Take 1 is the winner, but that verse 2 has to come from take 3 and the first chorus from take 2 and there's no good 2nd chorus so I'll cut and paste the one from take 2 again... etc... which is what I call comping.
I will do that for vocals because I need to usually, being a crap singer...
But it's not a religion... I do what works for me and I figure if I can't play the damn thing well enough to get complete takes then I shouldn't be recording it yet...
