That's strictly on the top end ... no screwing around before 1100'.

That sounds about right. My calculations were that you had to scrub 20 mph over the last 130 ft. to scrub a tenth. So, if you can scrub 26 mph over a slightly shorter distance, say about 90 ft., you would scrub about a tenth.
All that said, I think doing so you're starting to approach the danger area.
Bob, I don't think anyone on here would have an issue with somebody scrubbing 10 mph and a few hundredths. It's the examples like above that I generally don't care for. But, even then, I can't put a specific number on it. If somebody timed the parachute right and hit the brakes simultaneously 120 ft. before the finish line, I'm guessing they could scrub a good amount of speed, and, more importantly, do it safely.
All I know is that you'll never catch me pounding the brakes at the finish line. Hitting them, sure. But pounding them? Nope...it's just not worth it to me.
