It would be interesting to see how many users are up 75 BTC on payouts versus blocks solved. It most certainly won't be 5%. I doubt it is 1 in 1000. And anyone in that kind of extreme situation should be scrutinized.
I think this illustrates why the multipool situation was unique. The magnitude of the pool percentage was very high as was the magnitude of his bad luck. Presence or absence of malfeasance aside, this combination made a few of us uneasy.
Maybe the per-user CDF should only appear for users who meet a percentage criteria? Like users over 10%(?) of the pool should always have their CDF visible on the site. I think most of us would get used to the ebb and flow of the CDF of the the big actors who are clearly here to find blocks. For the newbies and the torch n' pitchfork crowd, the rest of us can talk them off the ledge.
I
really don't want to have a witch-o-meter on the site, but I also can't afford to be robbed blind. I am in favor of a rational discussion of possible solutions here. I think my idea has merit and I'd like the Doc to consider it or some variation.
