doesnt matter so much if its bvb or c/o vs btn imo, but ive seen it alot more at bvb than c/o vs btn, I've done it q a bit at bvb but never at c/o vs btn afair.
Of course it matters. Variables like opening range, f3bet, 4bet range all matter. Regardless, if your horse is doing this, tell them to get a grip. 3b/4b stuff is simple maths.
Link to maths, please.
SkolSuper claims elsewhere that he has a game optimal solution (or at least some useful partial solution) for 3betting/4betting/5betting. I'd like to see it..
Not sure I like the note of incredulity in your post, but whatever, I wrote this on the subject a few years ago:
