Those figures seem to be for a temperature probe with a recovery factor of 0.8. I.e. measuring SAT + 80% RR.
So in our case the 0.8 probe would show a RAT of -19°C, sensing 80% of the RR (26°), giving a SAT of -45°C.
The 1.0 probe would show a RAT of -13°C, sensing 100% of the RR (32°), also giving us a SAT of -45°C.
Well that's my theory, anyway.
