All the data tables and graphs refere to merlin XX equipped aircraft.

The RAE's use of a single chart given the absence of any differientiation between power levels makes perfect sense with the Merlin XX predictions.
The Merlin XX was predicted to maintain similar power from sea level to 20,000 feet.
1020 Hp at Sea Level and 1075HP at 20000 feet:
