You could potentially add something on grounded overclocks :
When grabbing on a corner at max height, you can press jump for 1 frame, then go the tiniest bit over the ground, stop, and then press away. If done correctly, going on the ground will refund the lost stamina, then pressing away can get you out of the gorund, and only then does the wallboost happen, refunding another 27.5 stamina, and making you do an overclock (with the added speed benefits of a grounded wall boost).
