I second Craig here. The German and British definitions of the length of the Battle are different. I can also see some inaccuracies on the RAF side of things.

Also one needs to keep in mind if you are going to try to use this as a comparative study (and you may not be) is the fact that criteria for claims were different between the RAF and the Luftwaffe.

However I congratulate you on the scope of what you are trying to achieve, not the easiest of undertakings.
