I've been thinking about the DOW and large trials.
For those trials with entries greater than or equal to 100, using the DOW as currently written to determine the number of the starting dog does not give every dog an equal chance of running first.
If a stake has 100 or more dogs, the highest possible starting number is 99. Dogs with a number of 100 or greater are guaranteed not to be first in the running order.
An easy fix for this unfairness would be to use the last 3 digits of the DOW when entries are 100 or greater.
