what is an hour of reward? I understand reward in terms of some form of a joyful/insightful/... experience, not in terms of time
"Most programs today yield insight only after days or weeks of unrewarded effort. I want an hour of reward for an hour (or three) of effort."
So they want to be rewarded with at least an hour of saved time, or more productive time, for one (or few) hours they put in, instead of spending weeks to reap rewards.
