Moe I understand what you are saying, it just isn't wise for me to do that at this point. It's not really anything specific to AFL, it's just that I don't have a large enough sample to find out where my advantages lie and how accurate the perceived advantages are.

If I think one team should be +20, and they are +40, you'd think it would warrant a larger bet. Thing is maybe I have that match wrong, which means I'd be overbetting.

Until you can be reasonably sure of the size of your perceived advantages, using different stake sizes is quite dangerous.

Flatbetting at first is always the best way to go. If your system is profitable, then you will profit.
