My question is what do we do when the time is negative? Look at the bottom of the chart, spread sheet. If we are doing this wrong, please help us.
I think that you need an additional column. When the original ball comes into the goal, there are at that time 0 "other" unexpired balls in the station. So at time = 120, the original ball must be returned at 109 seconds.

Here is the formula from the DOGMA document

T expire (x) = T score – { 11 + (4 * # other unexpired balls currently in Station) }

Document is found here: http://www.usfirst.org/uploadedFiles...DOGMA_RevA.pdf

Your main question about negative time, still applies, and while I would believe that you don't have to return a ball to the field that has a negative time associated with it - it still would be good for GDC to address through the Q&A forum.

Thanks!

Steve
