I asked this question recently, unfortunately it did not get me closer to an actionable answer. Of course clothes get damaged and stuff is in the lint drawer, but it is a huge difference between losing the longevity by a 1% and 30%. Any actual research would be tremendously helpful.

somewhat close (they basically measure shedding, although mainly about speed of drum importance (seems like both fixed fast rotation or very slow are better), but it doesn’t seem there is dramatic increase over cycles (the first is the worst, evidently, see fig 5), but they don’t do 100 cycles, you can search around in theirs citations for more info probably.
