Keep on doing what you're doing. Dan John talks about nudging up that 80% weight over time and setting a "PR without maxing." If you stick to your sets of five and progress patiently, eventually you'll be doing fives with your current "theoretical max".While my "estimated 1RM" based on lifting 295 x 5 and a calculator shows about 350, I follow my program and the highest I have ever loaded on the bar is 315 so well short of my theoretical max. Unless I was going to compete, going any higher doesn't help me focus on form and gaining strength, and would only serve to stroke my ego and while it's tempting, I have resisted, haha.
You can learn to grind without testing a true 1RM.
