Not sure about the Condit fight, but Nick tested at 175 ng/mL for the Gomi fight, and Alamo also made a huge deal out of it and acted like it was basically the highest result he'd ever seen. I'd bet most other athletes who've tested positive come in significantly lower. He was probably lower for Condit too.
His helmet was stifling, it narrowed his vision. And he must see far. His shield was heavy. It threw him off balance. And his target is far away.
