Yeah, historical reasons maybe, I think. I checked BMP280, which states temperature and pressure compensation, I didn't find this formula. I'll take time to check other spec later. Hope anyone...

I did checked following chip spec. No clue to the formula. 1. BARO_BMP085 2. BARO_MS5611 3. BARO_BMP280 4. BARO_LPS25H 5. BARO_QMP6988 6. BARO_BMP388 7. BARO_DPS310

Well, I'm NOT quite sure about GPS altitude's accuracy （10 or 5 meters???）. And I'm quite sure about baro's relative altitude accuracy flying just a few meters above the ground....

I know 4.4 will introduce RTH features (well, let's say more advanced GPS resucure feature). That's gonna handle what I concerns above. So is there any feature #??? avaliable, or...

I will try when released, or this ticket is attached to specific git commit. Currently, I didn't follow the 4.4 master, so I'm NOT sure about the status of the...

@sugaarK Is there any way to export data to excel or text format from bbl log file? so that we can analyze the data?

@KarateBrot CSV works for me. Thanks.
