Over on another thread Alberto is claiming Bismarck developed her fastest rate after PoW turned away but a year ago you were saying the opposite:
Between 25 to 30 seconds is ok in my personal opinion.
Still be very careful about the guns reloading time and the real rate of fire that Bismarck was keeping that morning.
Reasons not to waste too many ammunitions were many, ... and I think that Kvt Kpt Schneider was carefully firing his guns looking at the number of time he fired them, ... and the ammunition expenditure from 05.55 until 06.09, ... only 93 shells.
If you look again my table you will see that average each gun fired one shot every minute
But averages are meaningless. When the range and time of flight are short, and you are hitting why would you sit around for 30 seconds after each shot? That is not carefully evaluating anything. If your fire control solution is not perfect, the longer you wait, the further out you are when you do eventually shoot. When the range and time of flight are short, and you are hitting you conserve ammunition by shooting as fast as loading times allow.
Why when you are turning hard and heeling over and your guns are struggling to keep up with change of direction and your target is obscured by smoke and also turning hard and your spotting is irrelevant by the time the next solution is required, would you fire at maximum rate as supposedly shown on the film? Of course not.
Because your timetable is fundamentally flawed and always has been.
Alberto has been reproducing his Tedious Table over and over and asserts that more than the single value 93 shots is real, and not guessed or made-up in the Bismarck line. We know 108 "ordered" shots is assumed/made-up. Dunmunro disputes the first shot time starting the apocryphal 14 minute period and the cease fire time of 06:09 comes from where? PG 's cease fire order is given as 06:09
, but that does not mean she actually fired her last salvo at that time. During about 14 minutes Bismarck may have fired at close to her minimum reloading time as you have mentioned above or may have stopped firing altogether, as PoW did when turning at maximum rate. Dividing shots fired into available seconds is the crudest of crude approximations, and disproved by the film even if it does run a little fast.
There is a photo from PG of Bismarck having just fired a salvo involving both fore and aft turret groups when immediately between PG and her target, judging by Bismarck's barrel alignment. A salvo, possibly an 8 gun broadside, has probably been fired a few seconds before 06:09. This says nothing at all about the timing of salvoes before that. It does not tell us when Cease Fire was ordered in Bismarck.
The Baron does not say when Bismarck fired her last salvo, only the Schmalenbach map, derided by yourself, has the legend but does that apply to Bismarck or PG? So the 840 seconds are not supported by any original source.
All the best
