excellent points, but I have to disagree with number 7
in addition to the concept of
committing to the mix, printing a slew of vocal ups and downs and guitar ups and downs etc is simply a waste of time.
your recall may indeed ask for Vocal Up, but they will invariably ask for at least one other thing.
will it be guitar up or down? more bass? less snare?
more reverb on the hi-hat?
vocal up with guitar up, vocal up with guitar down, vocal up with guitar the same ...

then 3 vocal downs with guitars up and down and the same
then the bass and vocals...
then the keyboards and vocals...
then the various combinations of 3 instruments in all their up and down glory...
The permutations are endless. You can try to cover all the bases, but you never will.
Wait for the recall, see what they want, and do it then.
