There is only one situation in which it is acceptable for the pass/fail racer to accelerate or attempt to move up through the field, and that’s at the beginning of any sort of incline. This is a widely-known rule, but it’s one of the few that’s actually designed for the pass/fail racer and so it bears repeating here. What you want to do is move to the front of the group at the start of the climb so that as you continue up it you can slowly drift back through the group instead of struggling to stay on. Hopefully, by the time you get to the top of the incline you haven’t already been spit out the back.

if you find yourself dropped and alone, you stop racing.
2nd point first:
If I had been told that when I first started racing, I would not have finished a race for something like two or more years.
As for the hill tactic, I am aware of this but I didn't know that other riders would be willing to let me ride this way without misinterpreting my motives.
Question: when a hill is teamed up with a medium or worse head wind, what does the weaker rider do then?
If I move to the front at the bottom of the hill, the others may well choose to just sit behind me and draft. Especially in F grade.
