Tony: you clipped off part of the formula but you did point me to the right section which is half the battle; so thanks.

I would summarize the rule like this: The scored time element for determining speed when undertime is 90% based on min time and 10% based on time on course. I didn't see anything about that rule changing for guys that are more than 15 minutes under time as Steve Leonard suggested.

The formula has a provision that further reduces the scored time element if the pilot has flown more than 85% of the maximum task distance. In that case the scale slides between 10% / 90% at and below the 85% threshold to 100% / 0% for the pilot that flies to the very back of every turn area. The effect then is that you are entirely scored based on time on course as long as you go to the very back of all the turn areas. This clearly is intended to keep a valid competition going in the case that the CD has called too short of a task for the prescribed minimum time.

By typing out this summary, maybe I'll be able to remember it for a couple weeks anyway.

JJ: Sorry, I suppose we hijacked your original question. Anyone able to respond to JJ's original question should please do so.
