thanks to Mr.Jurens and to Byron Angel for their useful clarifications and interesting calculations.
Back however to the Bismarck track and firing, it is clear that Mr.Wadinga has been left alone by all his co-deniers with his theory that the correct battlemap is the 1990 one, published in the last edition of the Baron's book.
However, he has not yet admitted he was wrong supporting this last map as demonstrated by (my italic for a slight correction):
"I guess any sane person should be able to see that on course 270° Bismarck would NOT have closed the range vs Hood and PoW. Instead, she passed from 21150 yards at 05:56:10 (salvo 6 landing) to 16450 yards at 6:00:00 (salvo 13 landing). BOTH salvo 6 and 13 were straddles, therefore this distance change is surely CORRECT and Mr.Wadinga is once again rubbished in his desperate attempt to find a weak point in Antonio's reconstruction, by far the best available one .
Is Mr.Wadinga able to realize (despite his mathematical deficiency...) that such a closure rate (almost 5000 yards in 4 minutes) is simply physically impossible with Bismarck on course 270°?
Were Hood and PoW flying on the water @ 55+ knots following Bismarck in an (almost) stern chase ?
Therefore simply the 1990 map is TOTALLY WRONG (+ methodologically incorrect, as it does not respect even PG own track).
End of story (at least if Mr.Wadinga doesn't want to propose another theory about PoW firing against...fishes due to a "mirage" while Hood was hitting Bismarck instead.... ... or that it was BC1 running north toward BS, as he ridiculously tried to state in his delirious post above "
Instead of changing thread and subject, this guy should answer or finally... SHUT-UP, admitting the correct map is the 80's Baron/Schmalenbach/Rohwer one, very similar, even if less detailed, to Antonio's 2005 one !
He simply cannot run away as he did already with the set of bearings chosen by Antonio for the reconstruction of the battle....
Anybody else wants to support the theory that Bismarck could have been on course 270° from 5:55 till 6:00 ?
