Would there be any idea in adding some way to calibrate the temperature on the 5X? For example if you know the exact room temperature at a given time, would it be possible to input that and it would automatically deduct you body temperature from that value = allowing you to see either the room temperature or your body temperature. I of course understand that the room temperature can vary a lot, but could the weather data on the watch be incorporated to this equation to dynamically change the value? Would this be too complex or impossible?
Jim do you think the F5 is capable of taking temp from tempe when factoring baro - elev values? Or... does it still the internal thermometer even in presence of the tempe, as far as elevation calculation are concerned?
Tempe is the best way to got for temperature, but slow due to Garmin implementation. Watch scans for Tempe signal almost once in two minutes...
What I understand is you mean extracting the room temperature from watch temperature reading and use the result value as a correction value in future readings, so that watch will give more accurate temperature data; which is not functional in real life at the moment due to body temperature. It can be done with a CIQ app or widget but I don't think this will work well if this is what you want. Watch can be in different temperatures depending on what you're doing or on your movement.
I think altimeter accuracy issue is related more to the software side. It needs better algorithms to decide when to increase or decrease elevation instead of changing air pressure. I have Fenix 5X and had Fenix 3. My personal experience with these watches say, Fenix 5X altimeter is worse than Fenix 3 altimeter. It not only tracks elevation changes worse, also tracks counted stairs worse too. What I see in the watch altimeter when going downstairs is, it keeps the elevation same and increases in the end, or increases while walking. Then when I reached end it calculates again and decreases the elevation; thus deciding the elevation after the movement or sth. like that. Air pressure change during this part may easily effect the elevation reading, I'm OK with that. However, even when stable sitting in my bed, it decreases or increases elevation. :D My F3 did it too but during times with extreme pressure change. I don't want to play with it continuously changing between barometer or altimeter mode. I just want its altimeter work as good as Fenix 3. However, in GPS activities elevation graph is mostly good. Sometimes 1 or 2 meters lose, in 60KM cycling activity.
We did have a baro calibration IQ and then Garmin updated their baro with the calibration feature. The problem, should an IQ be built to use the tempe's values instead of internal thermo, during an activity (which is where correct altitude matters the most) would use up one of the only 2 slots we have available for IQ data fields.
... on top of that, it's outrageous that the F3 could hold 5 and the F5 can only hold 2.
