True. But since "results" aren't exactly quantifiable, how can they get steady value for their money?

Is result A equal to result B or result Q? If results M, N, and O are all equal, how many M/N/O results does it take to earn one week's worth of paycheck?

What if they decide that they're paying too much for M/N/O results, and want at least 11 of those per week instead of the current 4?

What if you wait an entire week for the dumb assholes in the other department to deliver the specifications? Do you not get paid that week?

You're paid by the hour not because hours are the best way to measure accomplishments, but because it's easy to measure hours and difficult to measure anything else.
