I think it the primary thing would be the equalisation of the time line, in which the RAF has a huge benefit currently.

The present most modern luftwaffe fighter with these not armoured cocpit, DB 601 engine and MG-FF weapon enters service in early 1939, in Spanish Civil War* There are not an additional modification or a development on LW fighter.

The first Spitfire Mk II enters in service in Aug 1940. The Germans got the 109 E-7 in the same month. An Bf 109 E-4, DB 601/N engine and a MG-FF/M cannon were received already on the same summer. From E-4 the German airplanes were equipped with Armoured cocpit, automatic prop pitch and automatic water radiator system, and C3 (100 octane) fuel (to /N engine). I mention the most important ones only.

100 octane fuel to Spits? Yes, because RAF used it. No doubt. Constant speed props to all Spits? Yes, yes because RAF used it. DB601/N engines to E-7? No, because LW used it only small numbers? Come on guys, you believe it this correct? No need trick with numbers, only matter: existed, or did not exist (if we ran forward this much already into the time to Spit II).



*"Early in the year (1939) J/88 had recieved 40 new cannon-armed Bf 109 E fighters, and the outdated early marks were passed to Gruppo 5-G-5. On 5 March Mölders's replacement as leader of 3 Staffel." (Osprey Airwar3 - Christopher Shores: Spanish Civil War Air Forces, page 42)
