Respectfully, it’s nothing new. Weightlifting industry has known this concept forever, it’s often just expressed as charts rather than graphs, as it is easier to interpret.
But they go even a step further, they extend into 3 dimensions to also add body weight as a variable. So your graph would really have to be a 3D volume. Because different levels of body weight have different capabilities.
Respectfully, his graph does not need 3 dimensions because it's a personal spreadsheet he uses just for his own training, so he can just display the data for his exact body weight.
