I have spent the majority of today trying to fix my Disto. I've finally done it! I didn't find this solution online so figured I'd share it...
So it had recently been dropped and the calibration was thrown massively out of whack - i.e. there were 60-80? of change in the compass reading when I rolled the Disto - pointing it in the same direction.
I'm not sure if this is the case for Pocket Topo, but with TopoDroid (Android OS) calibration data is normally grouped together automatically as the software just matches up similar looking readings.
It seemed with my semi broken Disto, TopoDroid was having working out which readings were which, due to the huge difference in readings that were supposed to be similar, leading to the error message (not enough data) even though I was absolutely sure I had taken all 56 readings correctly! Had the readings had a slightly smaller variance, things would have been okay, TopoDroid allows you to simply up the threshold on what it considers an acceptable variance for one group of 4 data sets. However it was the case that I couldn't do this.
Turns out it is possible to manually group the data by going down the list of 56 readings on the calibrations screen pressing on each individual one and numbering them like so... 1111,2222,3333,4444,5555 and so on for all 56 readings. After doing this the disto only had a 5? deviance while being rolled. Allowing me to calibrate it more precisely and get it to below 1? variance in the end.
