Cartain days more profitable than others?

[Rolen]

I was browsing my SNG data and came across this : Playing during the mid weekdays (tues wednes thurs) my ROI is almost 20 points higher (!) than the other days of the week. Now, I only have 750 tourneys logged so this has little significance, but it got me wondering..There HAS to be an optimal day to play, one where for whatever reason the fish are out in greater numbers. Does anyone with a few 0000's more SNGs logged have any interesting findings here?
