I have been looking to expand my portfolio, not in a big way but in a more rounded way i.e more sport systems as I am currently only doing horseracing.

However after doing some research on other things I am lost, trying mine data from other sports such as greyhound racing is proving difficult, there is such a lot to learn, and it ha made me appreciate how much I have learnt in the horseracing field, does anyone have any tips on other sports such as greyhound racing or anything else etc.

Im not really looking to buy systems as I like to try and keep my things as unique as I can as hopefully for the future there would be less chance of future burnout from the odds dropping due to numerous betters increasing stakes on working systems.
