EDIT: just got an email back suggesting the same multiple sd card workaround. I wouldn't care too much, except that the new 1.3.3 takes ~90 seconds to load at each boot, whereas the the old ones (1.2.4, 1.5.5) take <5 seconds. I wouldn't mind helping with your software projects, and I'm sure there are many like me who would give valuable contributions. I've had it on my todo to for some time to make some scripts for post-processing shot track files. A weighted least squares, with normalized SNRs, in the neighborhood of each desired distance, gives an almost exact result to their velocities. The small variation is likely due to how they normalize the SNRs to create weights, or their threshold/criteria for throwing out outlier signals, etc.
a laptop app would be nice too.
