"There is a finite (relatively small) number of concepts necessary to mastering git." This is only partly true. The degree of variation and options in the command line actually fiddles with that 'simplicity' quite fundamentally. Even if one has a 'clear understanding of the concepts' - the commands don't necessarily map clearly to that model. And there are so many commands, so many little variations.
