I’ll share a little with this forum.
Here’s what you need to have a winning portfolio with AFL betting. You need to win on average over 52.5% at average odds of $1.90. (The average bookmaker margins in Australia are 4.9%)
You’ll want to start with a minimum range of parameters so you don’t overwhelm yourself and you can verify that the parameters that you’re taking into consideration are actually statistically significant.

If any of you want to share what parameters/statistics you personally watch we are all ears.
