How many multi sng\'s till good guess on ROI?
 

I have heard a lot of talk about how you need to play 1000 1 table sng's to have an even semi-accuarate idea of what your real ROI is, I was wondering how many 18 or 27 person sng's I would have to play to get the same confidence of the accuracy of my ROI numbers. Any help would be HUGE! thanks.

Check out this link from the SnG FAQ.

thank you for this site, I might not understand these charts right but it seems that this chart is just for single table sit and go's, is there a similar chart for 18 or 27 person sng's?

Standard deviations for multitable tournaments may be slightly more sensitive to your playing style and ability than is the case for single table SNGs.

I don't record all SNGs I play, but after 15 multitable SNGs on PokerStars (6 3-table, 9 2-table), my SD is 2.6 buy-ins/tournament. I would estimate that after n tournament, the standard deviation of my ROI would be about 260%/sqrt(n). By contrast, my standard deviation for single table SNGs is about 1.7.

Thanks,good info!

Taking the simplistic approach of assuming you have a 1/n chance of finishing in any seat in a tournament...

The standard 5-3-2 payout structure has a SD of 1.67 buyins. At UB a 20-table SnG still pays only 3 places with double the prizes, for a SD of 2.82 buyins. I have no experience with other sites' multi-table SnGs.

For 1-table SnGs I use a rough rule of thumb that I expect each tournament to run about an hour, and based on the "10 BB/hr" rule for ring games, I equate an hour of $1/2 to a $10 SnG, an hour of $2/4 to a $20 or $25 SnG, etc.

If the average length of a 2-table SnG is between 1 1/2 and 2 hours, you can continue to treat a multitable SnG as representing similar variance to the same amount of time in a ring game with a big bet 1/5 of the SnG buyin.
