I like telemetry call outs for battery and time
Well the 100Hz rate will still allow for that just not at a super high refresh rate
I run at 333Hz because I use a radiomaster gps module on my planes and like to record at every .5 seconds for more detailed data after the flight and 100Hz just doesn't have the telemetry throughput to achieve that .5 seconds update interval without cutting back too much on control signals in my personal opinion
For like battery telemetry and link quality the lower 100Hz rate at the standard telemetry ratio is more than enough to get a 1 second or so update interval
I did see that the newer versions of ELRS added the capability for transmitting more advanced telemetry data like "cells" which for my FrSky sensors was able to track the individual cell voltages and total pack voltage from the balance lead and do actual lowest cell or cell deviation callouts on the radio with some set up
Lots of blabbering to say I also like telemetry and am excited for new tech on the horizon
