Sure, except that if say a group of juniors knows they're starting on a 1000'+ hole, that 7 sounds better than a 9 or 10. Then we're giving incentive to skip that hole and show up on the next one. If you set par correctly, that's a par 5 and you get a score of 9 for missing that hole. Otherwise missing a tough par 5 gets the same penalty as missing an easy deuce hole.
On a collision course with 1000 courses, the only variable is time.
