My goal has been 90 and I do tend to hit it; I haven't been monitoring lately so maybe it dropped.
I would do that ----AND-----study if the saddle is in the right position. Your leg should be almost straight in pedal down position and the knee more or less over the crank center on average. There are a lot of threads on this BF which claim that saddle position and proper bike size are very important.
I found the comfort of a size 58 bike to be dramatic better than a size 60 bike (for my size). I could not believe it. It is only 2 cm. That makes a big difference in ability to spin and keep even pressure on your knee.
I would avoid jerky push pull if I were you.
Suggestion: See if you can get your hands on a good loaner bike. Perhaps in a bike club? Or an accommodating LBS?
