I responded to you privately but for everyone else generally if the game is fully working I would avoid resurfacing until absolutely necessary.
Gamecube sucess rate is pretty good but I have never kept track of percentages.
Well the ones I listed still mostly work after resurface. Lot of it has to do with how thin the disc is and what quality the discs are. I only run Gamecube, Sega CD, Saturn, and Dreamcast on the medium setting.
