Took a look at my data files and getting about 10hz from GPS, but only 3hz from OBD. Although resolution is better with GPS the video speedometer is NOT as smooth as OBD. Is this due to inaccuracy of GPS? The discrepancy can be fairly large at times. I'm guess OBD is more accurate despite the 1/3 resolution?
And speed data in app seems to be GPS... anyway to choose OBD?
I think trackaddicts is awesome!!! Can't wait for the best theoretical lap feature
