BHI160 and BMM150 accuracy definition for SW API what does this mean

[owain-incus]

Can someone please explain the meaning of the "accuracy" value given back in the SW API's for most sensor measurements for BHI160 and BMM150. I undertstand the algorithms train themselves to try and minimise errors and maximise accuracy.

We are currently reseting the whole chip complex and re'initialising between taking measurements. I think this is probably wrong; meaning we would always start  sampling from a low accuracy point. How long does sensor complex have to be running to reach a state of best accuracy?

I have seen a definition was posted here for one of the other sensors.

Is this defined anywhere for the BHI160 & BMM150?

Did not like extension .csv; so here as .xls

We have just made another log using the same system; but this time we logged for aroun 32 minutes.
Gyros and Accelerometer DO start reporting high accuracy; but this is after about 5 minutes.
