The key to any depreciation of strength through your sets is more rest. Most people don't rest long enough for heavy compounds.

When I say heavy, I don't mean lots of weight on the bar. I just mean, enough weight such that your CNS is significantly taxed as to take a significant toll during the set. This usually happens when you're working in the near maximal effort range. This is especially common when you're using linear progression since you'll be pushing your limits frequently.

At least when working in the 3-6 set range. What I recommend is:

OHP: 3-4 minutes
Bench press: 3-4 minutes
Squat: 5 minutes
Deadlift: 6 minutes

Unless you're just starting out and working extremely submaximally.
