Gday All

I don't post much but look in .

I am testing a lay system on paper , since 9 april 2010 it has had 383 selections ( missed some days and weekends ) upto yesterday.
These are the stats from the software TSM ( i put the data in )
Total bets 383
Total wins (losses) 346
SR 90.34%
Required SR 87.1%
average odds $7.7
Level stakes it returns 3.96%

My question is - how many bets would i need before i would consider the results to be stable.

To set the record straight from day one, I am not trying to sell anything.
