Hi Peter,
Thank you for posting this question.
It sounds like you're seeing a larger than expected number of Major Deviations with your Agras T25 and T30 batteries.
This appears to be normal for other Agras drones and we may change the Major Deviation calculation for Agras batteries.
It'd be helpful to have your AirData email, as well as any specific batteries or flights you'd like us to look into.
Once we have this info, we'll raise this in discussion with our engineering team.
Thank you.
Best Regards,
Tom
