1)The authors of these articles are respected engineers and fuel technicians who are properly qualified to know how much power the Merlin III could generate on 100 octane fuel.

2)Rolls-Royce were already building Merlins that could run on 100 octane fuel in 1938.

9,500ft., 1,285 h.p. with 1,320 h.p. available for take-off....The maximum potential output of the Merlin II is 1,800 h.p..."

3) Not forgetting either that on August 7 1937 Rolls Royce had a "more-or-less standard Merlin II, running at 18 pounds boost on a special mixture of straight-run gasoline, benzol and methanol with a dash of tetraethyl lead, achieved an output of 1,536 hp at 2,850 rpm over a four minute run." (this was used for the Speed Spitfire). Price The Spitfire Story 2010 p. 107. Ergo the engine was already strong enough to take the extra power.
