@ Alberto Virtuani,
many thanks Alberto for your nice compliments
You correctly wrote :
However, IMHO, due to the fact that PoW salvo 20 was fired by one of the same guns that fired salvo 19 (Y1 or Y4), and that this salvo landed at 6:03:25, as per photo NH69731, I would not assume PoW salvo 20 could land before 6:03:55 (giving at least 30 seconds to reload the same gun as per theoretical RoF of British 14"). What do you think ? Does this match with the other evidences ?
Based on the above assumption of 30 seconds being the minimum reload time ( rate 2 shells each minute ) for the PoW guns ( Y1 or Y4 in this case ) we can move the PoW salvo 19th showed on photo Nh 69731 being fired at 06.03 and 00 seconds from the previous 06.03 and 10 seconds I was calculating before.
I obtained the previous time by subtracting 20 seconds from the salvo 20th that is the milestone reference being fired at 06.03 and 25 seconds, because 20 seconds is the time between salvo 20th and 21st, .... as we can see on the PG film, ... but now it is clear that it was not the real PoW guns reloading time since the gun that fired salvo 21st was another one not firing on salvo 20th, ... the Y3.
The salvo 20th from PoW landing at 06.03 and 45 seconds is the base reference in synch with PG battle map showing the Prinz Eugen first turn.
This movement of salvo 19th of 2 guns departing from PoW at 06:03:00 is perfectly in line with PoW gunnery plot map, which shows the Y turret local control salvos being fired starting at 06:03:00 exactly, ... and everybody can check the X they traced there.
I like to underline that the photo Nh 69731 not only shows the PoW salvo 19th Landing at 06:03:15 after 15 seconds flight time, ... but it shows also the Bismarck salvo 16th landing on PoW on the same moment, ... so we can assume Bismarck salvo 16th being fired at 06:03:00 and landing on PoW at 06:03 and 15 seconds as well.
PoW salvo 19th and Bismarck salvo 16th are in synch and have been fired almost simoultaneously.
But if Bismarck salvo 16th was fired at 06:03:00 ... and the salvo 17th we can see at the beginning of the PG film was fired at 06:03:29 seconds ... we have an interval of 29 seconds between the 2 salvos ... enough to make the turn of 50 degrees to starboard from course 220 to course 270 ... all seems to match well ...
Hope all is clear ... and thanks for the value add input. This is exactly what I am looking for to improve my work ...
