How often are your trackers calibrated for speed? How do you calibrate an iritrack?With satellite GPS deviation of + or - 5 miles an hour and having a position deviation also, how do you compensate for variance? What is the accuracy of your tracker? + or - how many miles per hour and how many feet is latitude and longitudal deviation? Is the racer that is accused of violation allowed to review their own tracker, public or private knowledge? Does low or high voltage affect the tracker? How much testing was involved before SCORE adopted iri? What is the failure rate of the tracker? Does the tracker use true north or magnetic north? Do all trackers have the same hard/software? Were you using a base station? How many Hz does the tracker use? Now this is the best question of all....IS SCORE compensated from iritrack or are all the funds for iritrack rental and use going to iritrack?
