How often should I discharge?

[k£v!n]

Ive just finished watching rctvlive and they featured discharging of cells, they recommended discharging and equalizing your cells after each use! To me that sounded a little too often so i thought i would check before I did anything! Im using GP 4300, I race once a week and about twice a month at events!

Any help is appreciated!

Thanks
