In our AMA district, our local enduro rules allow a check to vary from the .1 mile-even minute requirement up to + or - .1 mile from the correct mileage as measured from the last mileage marker. This is different from the AMA rules which call for a variance of .02 miles on check placement. Further, AMA allows for a challenge of any check whick requires the mileage be re-measured using the average of three bikes, preferably one being the bike that originated the mileage, and one being that of the protestor.
I have done some testing of this challenge with some of my friends over various mileage lengths from one to five miles. All of the riders are "A" enduro riders riding the same kind of bike and using the same odo setup. We have yet to get a mileage that agrees within the .02 guidelines. Usually, we see variances between the bikes from .03 to .08 miles depending on conditions and the mileage measured.
The AMA rule also calls for any check in which the average mileage of the three bikes exceeds the .02 variance to be changed to the status of an observation check. In my opinion, based on the testing I have done, almost any check can be challenged successfully. This means that the results in any enduro is subject to manipulation by riders who want to eliminate points at a particular check.
I would like to hear from other districts, their opinions and rules regarding this subject, as I am considering writing a rule change request for submission to the AMA. Thanks for your input.
