I don't understand this comment "compact cranks for lols" 90rpm at 50x11 would be ~32mph, if you are going that fast on a road bike for 10 miles then you really will be laughing...
Do you mean spinning out, or just that you felt you could have gone faster on a bigger gear? Not sure what cadence you think counts as spinning out, but 150rpm on 50/12 is 50mph. You do know that you can only save 12s/mile by going 10mph faster than that, don't you?
