Anti-Surfer Targeting

I have been tuning WhiteFang's gun lately and while I could get a lot of success in TCRM with genetic algorithms my AS targeting isn't improving a bit.

Thinking logically finding weights with genetic algorithm shouldn't be as effective against learning movement as they change how they move but I had though it would do better than some randomly assigned weights.

Currently the best score I have got is 69.36 with the current AS targeting which is just the main gun with 10 times the decay and lower K.

Any advice about how to tune it?
