I guess , that it must be that 5% of your uncertainity , though I am not sure about wether Lexan may go through a process of "aging" under certain circumstances(long exposure to sunlight or contact with solvents or chemicals or similar) , that may render it breakable
.
Many years ago I have made some three larger lures with Plexiglass lips from scrap(didn't know it better back then) , one accidentally slipped from my hand and fell tail first on the floor , the impact shock was enough to crack off the lip like laser-cut around the belly curve !
Thought , that the lip was damaged before , so I dropped a second lure intentionally the same way , and it happened again !
After I cut out all the three lips on my routing machine and replaced them with aluminium ones .
Good Luck , diemai
