Thanks! I've had a couple of very serious knee surgeries that have resulted in limited flexion due to scar tissue. So what you see there is literal rock bottom for me. The "instability" at the bottom you're seeing is also likely a result of the knee issue. I'm completely unaware of it as it's happening BTW. I know it's an artifiact of my lifting but I'm not sure it's enough of a problem to put a lot of energy into, given I'm still hitting new PR's in the gym.
