I thought that I'll make an average of 12 on my 2x2 for a video, so I made one, second, and so on... That's the best I could've get. I also made a video in the past few months where the average was better. Could anyone tell me what I started doing wrong?
Sometimes too much practice can be a bad thing. For me, practicing too much can make me stressed out and unable to get faster. Taking a break for a few days usually helps me get back into the swing of things. Good luck with getting faster!
Maybe you're just having a bad day. It happens to me every now and then, where no matter which cube I solve, I just can't get my times back to normal. Usually if I try the next day or maybe later that day, everything will go back to normal.
