Yeast Reuse

Has the procedure on yeast reuse changed in the recent years, or is the method of re pitching still same as it pertains to gravities? I.e. First beer 1.040, second 1.065, third 1.090, etc.
Wondering if I should build some new yeast instead of stealing some from a 1.064 batch for some smaller beers.

Stepping it up as you mentioned is probably the ideal, and I try to plan my brews out that way if I’m going to be repitching multiple times. But if yeast from a 1.064 beer is OK to pitch into a stressful, high-gravity wort, then I can’t imagine that it would have any trouble with some session brews.
