Chopping clock vs. starting clock

[ref18]

The key here is definite knowledge. In order to wipe off the basket you must know 2 things:

A:That the timer did not start the clock on your chop
B:That about 1 second has gone by since your chop.

If you know only one, i wouldn't wipe the points. If you know none, the score stands. If you know both, then the points are gone.
