"giving Heidemann more than one second to land the winning touch"

This seems the crucial point, and without having it specified it is hard to tell if this is a very serious oversight or very minor aspect. If Heidemann had 1.01 seconds instead of 1.0 to land a hit, this would be very minor. Whereas if Heidemann had a full minute of extra time, this would be major.

I'm not doing any extra research since this isn't too important to me -- but some crucial context is very clearly missing here.
