Thanks Crash - I'd just finished doing what I said in the previous post, ie putting it in at level stakes and finding out the max drawdown. Over the 2 years and 6000 odd selections, at level stakes the max it dropped below the highest point was 79 bets.

That's a bit of a losing streak (obviously there were winners within it) - if you had a bank of X and were betting 1% of bank, non reducing, you'd obviously be down to 21% of your top amount at that point.

I think the rising/falling 1% of bank is a good idea, waddya reckon?
