It has been discovered that occasionally GPS timing apps fail to record a contestant's time or records an incorrect time. The following Technical Bulletin outlines methods a Rally Committee may use to address this issue.

If a GPS app misses a contestant’s time or records an obviously incorrect time the rally committee may alleviate the problem by one of the following:

1. Discard the leg(s) from scoring for all contestants.
2. Adjust an individual contestant’s score. Two methods are allowed:
   • (Preferred) Arrival time recorded on a back-up device.
   • Adjust the contestant’s score to the average of their non-max scores (e.g. average of all other scores, the average of all scores in section where the error occurred, the average of the scores on the legs immediately preceding & the leg immediately following the leg(s) in question.)
3. In regard to Course Rallies, the contestant must state that the failure of the app was the direct cause of their error.
