Replying to Playing with a stop watch

i was playing with a stop watch today (something i do whenever i have a lab involving stopwatches) and i was seeing how many straight seconds i could go by stopping it on exact seconds <--- thats probably confusing but anyhow....i stopped it on 1.00 seconds, then stopped it at 2.00 seconds, then 3.00 seconds, but i totally blew it going for 4.00 (that is w/o resetting the watch time).

try it and see how far you can get, its not as hard as it may sound
