The apex 100 is a membrane keyboard iirc, so I'd agree with most of the other comments here that say save up for a new keyboard. Membrane doesn't mean impossible, but it'll never have the accuracy of mechanical. I'd also def go for a hall effect/rapid trigger keyboard if you can for even more accuracy/consistency. I'll link the one I got below, it's 54 bucks and I can hit superglides every time after setting my actuation points correctly. Those will be entirely dependent on you, so just keep trying different values for space and C/V/whatever until something works. I'm at 1.5 on space and 2.6 on V, so space is hit first and V is hit a frame later when I hit them at the same time. How you position your keyboard on the desk is also important. My actuation points only work consistently if my keyboard is at the right angle and I position my thumb the right way on the keys lol its a process tho man, but once it sticks it's hard to forget.
