Ok this will stay as main issue.
1. Number of aircraft clashing in the air, - RAF & LW
2. Usage of the different groups. and Luftflotten
3. Range of which RAF groups were vectored for interception.
4. Usage of Enigma to RAF high command (group leaders and Dowding)
And to some,,,,the outcome.
1. Claim by groups
2. Post war confirmed kills as compared to LW losses.
3. Blaims and theory, why Dowding and Park were demoted.
I'll post a link to the thread here anyway , when it pops up.
