S_Alexander: I think what’s going on is the fast analysis works like this: we take a quick hunch of all the moves, pick what we think are the top 3 (actual top three is somewhat subjective, or at least non determinstic). Then we do a full analysis on those three moves, and however the stats work out from that is what we use for the change in outcome. So, while not a perfect system, I think it tends to give pretty good results. I think looking at the full analysis, it’s quite possible that it got…

What happens is that it guesses the top three using pretty rubbish estimation, then it computes the actual score of those three moves and puts that as the percentages you see. So it had a wrong ‘hunch’.
