 I 
doubt that we could actually garner any significant statistics from the pull 
codes. (Truman - you're the mathemetician... what do you think?) The biggest 
enemy of statistical signficance is variation, and just consider the amount of 
variation there is with each L pull: The obvious ones are: state, region, 
temperature, terrain, speed, horse, rider, vet, type of lameness, cause of 
lameness, - then you should really consider - time of year, age of horse, 
age of rider, fitness of rider, pace, feed, shoeing method, conditioning level, 
rider experience, moon phase... etc. Having done research and tried to glean 
statistical significance from my work, I know how difficult it is. It would be 
very hard to (for example) find a statistically significant correlation between 
things that seem rather obvious - speed/temperature/Metabolic - or 
speed/terrain/Lame. If we were to eliminate all of the other variation factors, 
we might be able to say ' look, when you ride too fast on rocky terrain, your 
horse has a greater likelihood of becoming lame'. But once we factor in all the 
other contributing elements it just becomes common sense, not statistical 
significance.  
  
So 
Frank... I guess I agree with you. A simple DNF on the results would be 
adequate, and if AERC really wants meaningful data, we should come up with 
something else, such as a horse or rider tracking system (log 
book).
