I think what a thrower does in practice is probably a better indicator of skill and technique than at a games where you've driven several hours and left home at zero dark thirty or slept on a crappy motel bed, eaten fast food before hand, and are looking forward to a long drive home at the end of the day.

Just saying that at practice the conditions are usually optimal. Occasionally the adrenaline at a big games can help, tho. I usually threw sub-optimally (less than practice PRs) at the "little games" but almost always showed up big time for the games that really mattered. It's a matter of perspective. Throw to have fun and the "far" will take care of itself.
