Based on my experience:

1. Strength is not Linear.
2. Always evaluate your form at 3RM and 1RM. The moment your form starts failing, reduce your 1RM and slowly build strength again.
3. Your CNS plays a major role in Strength. So dont fry it all the time.

Strength will mature when you reach to a point where you can only increase 5lbs per year or lower for your lifts. You will feel like it takes forever to increase your lifts.
