First Week of SNG Stats - Comments?

[UMTerp]

I guess this is still a relatively small sample size, but I decided to give the Stars Turbo SNGs a run this week. Started with $200 in the account at the $15+$1's, and am arleady comfortably in the $25+$2, with the occasional shot at a $55+$5 (one of every ten SNG's right now).

Here are the numbers. Any general comments are appreciated, and also, is there some kind of formula I can plug these numbers into as to give a confidence interval for my true ROI? It has to be pretty likely at this point I can maintain a positive ROI, correct? I've been either 4-tabling or 6-tabling so far, and am looking into getting a dual monitor set-up to do more, because I find 6-tabling still relatively mindless work. 6-tabling is tough on my
laptop too because of all the overlap.

The relatlively low number of 4th place finishes jumps out at me. Am I due to get a bunch of those? Though the 5th place finishes seem disproportionally high too, so maybe they'll come out of them.

All comments from experience SNG players are much appreciated.

Keeping stats has helped me sooo much with my discipline. I wish I'd have done it months ago.
