Which assumption in the expected goals calculations do you disagree with?The issue with calculations based on assumptions is that the results are only as good as the assumptions themselves. Unless you can prove your assumption to actually be true, the results will always be questionable at best.
Because IMO, they are all fairly reasonable. Again, the assumptions in those calculations are core in the game of hockey.
If you ask a hockey coach what you should do to increase your chances of scoring a goal, they are going to say essentially the same thing as those calculations say will increase your chances of scoring a goal (shoot from a close distance in front of the net instead of from bad angles, crash on rebounds, try to have the puck cross the center of the ice before the shot).
