That cassette looks clean enough to eat off of.

Those little half-circle wear marks are not normal. I've never seen anything like it.

I see wear marks on ti and alloy sprockets all the time, but yeah, these in particular look deeper/more defined than most.

3200 km with same chain is bound to leave some martks on the most used sprockets, especially if a dfry lube or wax has been used. The tooth profile does not look worn. That chain is not an X11-SL.

Looks like he said he replaced an X11SL TiN with an 11.93 or something like that. Anyway, I don't know about most used sprockets. I could see sprockets 3-5 being used a lot, but 1,2? I do wonder if his indexing is so far off that the roller/pin articulation is really causing additional wear on the sides of the sprockets. I use Red cassettes, so I'm not familiar with how soft those five ti cogs really are.
