You can't be stuck on any hard rule for VD calculation; this is a lesson I've had to learn the hard way, more than once. It's a hit and miss at times, although I have a continual irregular sleep problem and other health concerns that you may not, so that complicates my mix.
My IDs are currently only 1 RMs, cycling between 1-3 sets, then increasing the weight by 5lbs. Perhaps try calculating your 1RM first, and then multiplying that by 80%.
Just one of many possibilities, and my suggestion is in NO way a tried n' true-for-most method. Like someone else commented, it's a personal thing. A Friday increase in weight, (or reps), doesn't necessarily mean an increase in Monday's weight. For me, Monday's weight stays the same, whether the previous Friday's 1RM was done for 1 set, two, or three), and that's working. . . for now. Keep an eye on the symptoms of over-training as well. If staleness keeps carrying over into Monday, you'll generally start being affected negatively in other areas (beyond the gym).
Any assistance exercises will add extra load as well. For example, a heavy LTE and/or Chin Up session on Monday will make a BP/THP/DL PR harder, (depending on your individual recovery abilities, of course.)
