Gaining faith in your stats

[Rob*]

Hi,

I'd like to voice a question that I've been puzzling over for a while.

At what stage do you begin to have a high degree of faith in your recorded stats of your SNG results?

Obviously looking at several hundred SNG's may not have allowed for variance and downswings. The question is how many SNGs would give you that high degree (let's say 95%+) of confidence that you were close to tracking your real ROI figure?

My own feeling is about 2,500 SNGs but I'd be interested to hear if anyone has a different view or even better, experience to back it up.

Rob.
