in such a close stich put .3 or .4 -- either way even nothing will change the outcome because of .1 seconds. it would be different if we had video replay to more accurately gauge the effects of .1 seconds but we do not so all we can go on is a very close estimation. I agree that the clock should stop with the whistle -- so in such a split of time you know its under 1 second and you should have an idea of whether its under .5 or not -- from there just massage it a bit
