I think the results depend not only on the days, but also on the hour of the week, and probably also on playing style. I am quite sure that I play at similar times as <3 does, and still have quite different graph.

Anyway, it is still amazing how big differences are there on different days. I usually skip one day per week, so maybe I should choose this day based on this graph

. The best option for this would be Friday.

Looking at <3's graph, it is also interesting, that he has higher ROI on Fridays than on Mondays, but much higher difference in profit than it would be expected based on difference in the number of played sngs on these days. Maybe the BI also effects the distribution of the expected ROI on different days?

Anyway, the samples are still small. I am also not sure, that Mondays really mean Mondays, and not Sunday (US time) nights. I have found this time to be most profitable (and also Saturday nights, US time).

Personally I think, that the results may reflect the relative number of regs on these days, and the standard deviation of the ROI of a given player, when different days are compared, simply reflects the goodness of his table selection. (with decent sample of course)
