The
general public version of flight aware says 02:01 and goes from 1980m at 415kph to 1620m at 25kph
and apparently misleadingly
does not show that the ADSB signals were patchy.

I'm sorry, but I have no idea what you're talking about - I'm looking at exactly the same ADS-B data that's available to anyone else, at
https://flightaware.com/live/flight/.../YSRI/tracklog
ADS-B sends Airborne Position and Airborne Velocity data packets at roughly half-second intervals. That means that during the last 5 minutes of flight the aircraft would have sent approximately 600 transmissions.
The FlightAware data contains 11 of those 600 transmissions - that seems like a pretty good description of "patchy" to me, and that's why IMHO attempting to reach any conclusions based on the ADS-B data is ridiculous.
