So how do you know for sure that a particular software produces accurate

Exactly. Creating an accurate algorithm requires testing against
known data. In our case, the algorithms were developed testing
against carefully measured datasets, and stress tested against
common instrumentation errors such as static errors common
in our toys. In addition, I have tested our as-implemented
algorithms against data derived with the addition of heading
sensors.

Other algorithms may not have been so tested.

Hope this is helpful,

PS: Compasses don't work so good. Don't ask me how
we know.

PPS: These algorithms do not work well when wind changes
rapidly (flying into a seabreeze etc), or in extended straight
flight...
