Can someone tell me why the DJI flight Log doesnt record in Minutes and Degrees like other GPS devices ?

Position data is recorded in degrees and decimal degrees in your flight record.

I've always wondered why other devices use degrees and minutes and then decimal minutes instead of seconds, simple degrees with a decimal place seems much more sensible!

It is the same data, just a different way of representing it.
