Getting the samples to line up with the video has been much harder with the Hero 6's gpmf data compared to the Hero 5 in my tests so far.  The writing of the samples into a payload at the assumed times seems to be a lot more reliable with the hero 5.  I see a lot more samples spilling over into neighboring payloads with the hero 6.  Makes it difficult to make heads or tails of how to line anything up.  Fingers crossed for an improvement on this as it's really awesome to be able to make use of this gpmf data.  Thanks again for all your hard work.  It's very much appreciated.

All metadata within each payload was the data the arrived in that sampling window.  As data is not buffered, there is really no way for the data to drift, in a course sense.  Is it possible you having issues with clock extraction, to determine the sample rate of each sensor?"}}
