I would like to point out one major flaw with this. If you look at OP, Meowchan, he is the highest rated m+ player in the world. Nobody else has his score. Meaning not all of his top runs were with the same exact group. In the group I run with, we alternate between 5 or so different dps. Changing one class can dramatically change the way you want to execute things. You can have a general idea of "yes we go this way and this mob hurts" but you can't exactly mimic a previous run, especially one from a different week with different affixes.
