just found out how to alternate spam easier

im still not that good at it but i found the technique. basically i found out that if i put my thumb under my index fingers (both hands) and just start spamming i can do it faster and straighter (without it going up like it happens to me alot when i just do it normally). again take this with a grain of salt (or whatever the expression is, im only like 70% sure thats an existing saying sorry) because im not that good at it but i found that compared to just doing it normally it works better.
