Hi everyone!

I've been playing the 5,5$ 6 max sngs on ipoker for a while now and have the following finishing distribution over 1260 sngs sample with a 3.4% ROI:
1st 18.9
2nd 19.3
3rd 21.4
4th 18.1
5th 14.7
6th 7.7

Now what really bothers me are my 3rd place finishes where it seems I'm bubbling a bit too often and which directly correlates to my, let's be honest, too low of an ROI for the 5$ games. I know the sample is not nearly big enough, however I'm having similar problems on other accounts that my 3rd place finishes are 1-2% higher than 1st or 2nd. I would really be thankful if someone could point out what I'm doing wrong. Thanks
