Too many people confuse definite with accurate. They are not the same. There are case plays that establish that an officials count, no matter how accurate, is official, even if very inaccurate. If you have any count, even in 10ths, it can be used. It doesn't have to be anything more. Definite only means that you know you counted to a certain time, not that it is accurate or precise. If you feel comfortable counting parts of a second, the rules support it.
