Seven 10-day and one 20-day Goenka Course but no "good results"

I have attended seven 10-day and one 20-day Goenka course, but never experienced either the "subtle sensations" or the "free flow." I have stopped going to Goenka retreats because I get frustrated hearing about how after the first day I should be experiencing such and such, etc. I still practice anapana for a couple of hours a day and study the Dhamma, and am resigned to being apparently incapable of having these experiences, which they also say are not important, lol. However, Goenka talks about them over and over in the courses and about how various people get "good results." I wonder if others have this experience also, and how they have dealt with it.
