Reasonable Strength Loss/Pre-comp

I’m about 8 weeks out from my comp and I’m concerned I may be losing to much strength during the cutting cycle.

What is a reasonable amount of strength to lose?

For instance my leg strength seems to be effected the most.

315 for 5 reps

275 for 5 reps

I think it may be the added treadmill work that is doing this but I can’t excatly be sure.

Thanks in advance for any help.
