I prefer doing it piecemeal to see what's happening when along the way.

Again, I prefer incremental steps so it's more obvious what any diagnostics
are referring to, if they should appear.

True, but if things get out of order for some reason, then you have a mess.

Thanks, already read that and bookmarked it quite a while ago.
