Super SNG tracker question

Hello everyone please be gentle but I have a question about some of the data that the SNG tracker spreadsheet gives you.

SD/tourney $181.70
Total SD $3,384.67
Winning Confidence 98.04%

65%, in 100 tourneys,
profit of $193.67 to $3,827.65

95%, in 100 tourneys,
profit of -$1,623.31 to $5,644.64

90.00% confidence in $/tourney
between $4.06 & $36.15

24.16% conf. in $/tourney +/-
$3.00 or, ROI +/- 2.8%

I know what everything above these lines are and I have heard of standard deviation before but im not entirely sure what that is I even tried looking it up but just a bunch of statitics stuff that I did not really understand. If someone doesnt mind spoonfeeding me some probably obvious answers I would appreciate it. Thanks in advance.

By itself, SD is not really good for a whole lot. With the payout structure in single-table tournaments, it's always going to be around 1.7 or 1.8 no matter how you play. There's not really much to spoonfeed other than what you'd find in a statistics book, and it's safe to say if you don't understand it you're really not missing much.

Your sample size is really too small for any of those stats to be meaningful anyway. The confidence intervals are fine (statistically, which still doesn't help you because they're so large) at uh... 20 or so and you've barely got that.

Those numbers are through my last 350 or so $100 SNGs. What exactly do the 65% conf, 95% and the 24.16% conf mean. Im pretty sure I know what the 90% conf one is meaning that 95% of the time i will make between $4 and $36 per tourny over my next 100 SNGs but I still dont understand the other 3.

And is the 98% winning confidence that I can beat the rake or positive overall not that I care about that just want to know what it all means.

Thanks

Not by my math... oh wait... nevermind.

I think you understand what the confidence intervals mean. It's just the same thing there a number of times to allow you to change different parameters. Any of the cells with grey backgrounds you can change, so you can change the "100" to "1000" and see what your 65% and 95% confidence intervals are over a different sample size. In the "90.00%" block, you can put in whatever percentage interval you want over 100 tournaments. In the "24.16%" block, you can change the +-$/tournament to whatever you want. Hope this helps.

Yes it does very much thank you

Yes, the winning confidence includes the rake. "Winning" is defined as beating the rake.
