in  case there are other newbies like me trying to do this on a budget-

i compared racechrono using my phone’s internal gps vs the transponder at the track.

my phone has a 1hz gps refresh rate


three sessions

track vs ( racechrono)

84.008 ..(83.98)

81.117.. (.81.35)


not bad for a free product, and adding an external 5hz gps sensor via bluetooth makes it way more accurate.
