I have noticed that recently I kept glancing at the timer subconsciously when I'm solving, which has been really detrimental to my times (averaging 16 past week). There was one time when I glanced at the timer and saw that I finished F2L at 8 seconds. Nevertheless me being the nervous wreck I am managed to end it at the 16 second mark. The scramble wasn't PB potential but I feel like I could have still got a 11 at least.
Anyhow, I've changed it so now the time doesn't update and my times are back — in the low 15s now. Hopefully I start progressing quicker soon.
And also not mess up any good scrams, that would be sad
