it will drop, you lost 8kgs and you say your PRs were 2 months ago. When was the last heavy squat workout? I find that anything over 1 week will start reducing your squat if you aren't lifting and roughly 2 weeks if you are doing oly lifts.
I have a meet in ~10 september. I plan to keep squatting till ~3-4 september. At that time I will only do high intensity, low volume squats. Something like trying to get a PR on the squat about one week before the meet.
I think in general the idea is when peaking for a meet, you reduce volume and you add frequency and intensity. Then the last week leading up to the meet you reduce intensity mainly but keep frequency up. Especially as someone who isn't very proficient with the technique you want to get as many good reps in as possible. After all its most likely that in the meet you(and me) will miss mainly due to technique errors rather than reaching strength limits.
