Like John (and many others I’m sure) I don’t edit that way either and seriously never thought anyone would. I have a friend that cuts on FCP and went to his office one day and his timeline was zoomed all the way out (over an hours worth) and he had gaps everywhere, plus sync issues (other than the first few minutes) and I had to inquire what that was all about 😀
Source monitor, make I/O marks, lay it in sequence, etc. seems to be the norm
