Is this “bad” technique? I find my top knuckle (or whatever it’s called? joint?) touches the string above when I try to hook my finger like in the illustration. I’m also not really “hooking” the string when I normally pop, I just put the side of my finger under the string and it slides off with some force when I rotate. FWIW I do have pretty small hands as well. Is this a bad habit that I should fix?
Don’t sweat it! Slap and pop technique is definitely not ‘one size fits all.’ If you’re getting a clean sound and it feels comfortable for your hand size, you’re probably doing just fine. Plenty of pro players use the side of the finger - it often helps with speed and a smoother release anyway. As long as it sounds good, it is good!
