I made what I would call a major discovery. I check my tip out before a tournament or match. But do I really inspected it. And most of it has to do with my eye sight. See my eyes are good from far ..but far from good. I need readers. So looking at the tip up close I saw well enough that it had good shape and if it needed chalk.. last night I played and determined my tip needed something my eyes couldn't confirm. . and under closer inspection I was right.
Now I will put on the readers to " inspect my tip" even during play. Losing a match for mis-cues is a mistake I won't make any time soon.
