an enchantment that rewards "fishing properly"

Automatic fishing farms give a lot of benefit for little effort; adding this, or something like it, would give people an incentive to put effort into fishing without completely destroying automatic fish farms. I'm not good with names, so let's just call it "Mastery." Mastery makes it so every 64 consecutive catches makes treasure 5% more common. It goes up until 90% of all catches are treasure (1,152 consecutive catches). The catch count can be shown by the experience bar. Alternatively, it can make the enchantment glow gradually more bluer until it is completely blue. Either one would work, but both together would probably be the best. Missing any catches will lose all or most progress. Different levels of Mastery change how much progress is lost. Mastery II saves 256 catches (20%)*, III saves 384 (30%)*, IV saves 512 (40%)*, and V saves 640 (50%)*. Mastery V is the maximum level and can only be attained through fishing. Mastery is incompatible with Luck of the Sea.
