Yep, if the point at which it hits 1.0 isn't the exact time it gets rendered, you don't get 1.0 and have to use tolerance. Problem there is getting the fudge factor low enough - and if you don't use a queue you don't know if the value is rising or falling, so it's as likely to trigger slightly early as slightly late.
Add into the mix the random variable of framerate - if you get a particularly slow frame near the peak, your tolerance has to be bigger to catch it. So you have tight tolerance and possibly fail to catch it sometimes, or you have a loose tolerance and sloppy timing.
