I'm REALLY confused right now.
According to Bulbapedia, Protect has a 50% decay with no minimum success rate. However, the other similar moves, Detect, Endure, Quick Guard, and Wide Guard, all have a 50% success rate if used successfully the previous turn. Does this mean the moves actually work differently, and if so, how does swapping between them affect Protect's success rate? Or are some of the Bulbapedia articles wrong?
I checked Smogon's Protect and Detect articles. They both say what Bulbapedia says for Protect, but the description is word for word identical so it is possible they assumed it was the same and just copy/pasted. Their Quick Guard, Wide Guard, and Endure pages also all say it decays constantly (until a very low minimum) however.
Someone should try to confirm this somehow because Protect and Detect are very widely used in URPG.
