I thought I'd better get a clock solve on my profile, so I bought one, learnt how to solve it and did some rudimentary practice down to about 30s.
Next comp I did two really terrible solves, full of howling mistakes - 1:06.87 and 1:27.04 - and obviously didn't make cutoff.
Then I realised I really hate clock and I'm never solving it again so I have a sup-1min PR forever.
Also dumb, I spent money getting far too good a clock, the Qiyi special edition. I gave it to my daughter who has a way better PR than me (44s) after doing like half a dozen solves. She also hates clock!
