Day 50 is not that early. A lot of people cut before that. Yes they are experienced with doing it and are comfortable doing it. The OP was comfortable cutting at day 50 so he did. Everyone has their own comfort level with cutting. It also depends on incubation temps. Day 50 may have been fine at higher temps whereas its earlier with lower temps...
