Inaccurate performance data for BOB fighters in COD comparing to RL data

Crumpp your theory require that in January 1942 at least one operational squadron used at least one Spitfire I aircraft.
Otherwise the restriction for operational units to 100 octane noted in the Pilot's Notes would be obsolete and by your theory would have been instantly removed and changed to "all units 87 octane fuel".
Please name at least one operational Squadron that used at least a one Spitfire I aircraft at that time.
