No doubt, this is interesting information, although the numbers are sort of overhelming...
But the numbers sometimes don't tell the exact true.
E.G.:
A lot of this material was lost in convoys. (The sailors' contribution is beyond believe, regarding the conditions, I think)
The quality of some of the war machines was not always great (read quiet few complaints of the pilots flying e.g. "new" Hurricanes that remembered the BOB)
And regarding the scale of the battles on the Eastern front, they get less significant, I believe
