Definitely interested to see how this turns out. My guess is that everybody was just universally slowed down and that something like 95 is the new 99 or something.
I will still contend that this is more of a sliders issue than a ratings issue. There isn't much of a difference at all in accuracy until you start to get down to 5 it seems like. Spreading out the ratings could help fix this a little bit but I think fixing the sliders would help more and you wouldn't have to change any ratings.
