Went through the same thing and honestly the speed watching was covering up the real problem, which was that I wasn't giving anything a fair shot because I was scared of wasting time. Try picking just three of those 2022 shows and doing the phone in the other room thing, but put the ones you were most excited about first so you actually want to pay attention.

35 degrees off is wild, that is basically a whole different recipe at that point. I get that ovens drift over time but I would have never guessed it could be that far from the dial without a thermometer to prove it. If it was mine I would probably just learn to set it lower and keep the cookies on the middle rack instead of paying a repair guy.

Did you also notice the pots drying out way faster once you started watering in the morning? Same thing happened to me on my little patio, and straw mulch on top cut my watering way down and stopped the splitting for good.
