It depends on what "normal 100%" means to you. The current In game 100% category goal is based on the in game stats / counter. It doesn't matter if you skip any objectives. Basically, just get the game to tell you that you finished game 100% (game shows you notification upon getting that).

The current "100%" category is based on individual missions/objectives which give % points. Once you complete all of them, it's done.

The category namings might sound confusing, but that's just the way it is.

regular 100% - complete everything in the game that gives you %

in-game 100% - do whatever you want until the game states you've achieved 100% (usually involves glitches)
