Not necessarily true Borntobesting. The button on my laptop requires me to engage before the cursor even approaches center of the "hit" zone. The meter will often appear fine and freeze just as it approaches the "hit" zone. The same thing holds true for the sudden spike.
I went to number 17 on Kiawah -9 for 7 holes when I had 2 sudden spikes at the very last second, then a freeze on the next shot and deposited 3 GI SD into the lake. It would be a wonderful thing if it always started that way so you could hold off, but my experience is very contrary to what you describe.
