FAST entries saw moderate growth from 2007-2011. The stacked chart shows a large Novice class and a small Masters class in the first year (as expected) and over a few years developing into a large Masters class. The reduction of entries in 2012 and 2013 is most likely due to the addition of Time 2 Beat.
In just two years, Time 2 Beat has bypassed FAST in terms of number of entries. This may be due to the fact that anyone can enter the class making it attractive to advanced competitors as well as trial secretaries (who only need to add one additional course building to the schedule).
This chart shows that Time 2 Beat is being offered at more events than the FAST class.
