Hi Duckman
My notes are based on material from Kogenluft monthly lists of losses and victories. Part of this material has been presented in earlier discussion as You mentioned....!
Regarding the British flyers involvement, You can see in the thread "The French connection" that even late in the War like Aug 1918 when the British had major offensive battles, the German lost more aircraft on the French front areas...so I am also rather convinced that the Germans throughout the War lost more aircraft against the French Air Service then against the British..but with the material I have today, I cant definitely proofe that..
The British did
NOT have an official victory system during the War, which makes their claims (also destroyed) more or less un-valid. I have some own theories why they did not "care" to have it, but it could be partly political reasons (in 1915).
It was the French which first developed a victory system for flyers as they already in the beginning of the War shot down ten times more aircraft in aerial battles then the German did. Their succeses also lead to the creation of Aces. The French victory system obviously changed from the origin and become slightly harder in 1916 and later. But their system basically "demanded" a destroyed enemy aircraft/balloon. I am however unsure if the French system in all cases demanded witnesses..
Most countries involved in the War "followed" the guidelines the French had developed but not all had the sharing system they had.
I would say that in general, that the French victories are valid in over 80 % (depending on German losses I am aware of) comparing to British
claims of destroyed which are less then 20 %......so here we are playing in two different leagues....
Italy is an interesting country regarding victories because they had "double" system. One for the media/press during the War and one officially which not was published until after the War...however also Italian victories definitely are valid over 80 %...
The conventional wisdom wisdom that the British was fighting mostly over German lines is "flat wrong". I have German documents for many months in 1918 for the Somme front were they reported that the British constantly flew sperre-flights and seldom crossed the lines. However the situation during battles were quite different(like April 1917) and from mid Aug 1918 until end when there more or less constant offensives and the Germans had huge problem with fuel...
Lastly I would say that the British in a German view were more agressive then the French and crossed the lines more frequently then the French did. The British also had very unusual Air Force compared to all other countries with a extreme high percent of fighters..
What people have to understand is that more than 80 % of all combats actually took place over what can be called the "Front line area"...

p.s. I havent counted which percent of British losses which fell in enemy lines from example TSTB, but that source ought to give a rough indication...or..?
