It measures milliseconds between taps, so the theoretical maximum is  
a count of only 1 mSec, eg 1KHz. Obviously frequency resolution is  
also limited to whole milliseconds, so the next frequency down (2  
mSecs) is 500Hz, then 333Hz, 250Hz, etc. As you can see the  
resolution is poor until you start getting down to the LFO  
frequencies it was intended for.
