Hello everybody
@Mr.Jurens: thanks for asking relevant questions.
Please see here the formulas used by McMullen (up to column9 except column3)
http://www.hmshood.org.uk/reference/off ... 09guns.htm) and the answers to your questions re.the table:
Column 1 -- Info about Hood are not enough to build a table. The "worse gunner" is the only evident thing that can be said about Hood shooting.
Column 2 -- Duration can be debated, within a tolerance of half minute. Else a credible alternative to what we know is needed.(*)
Column 3 -- Normalization in seconds, just used to make the other calculations easy to be understood here.
Column 4 -- Salvo defined as half armament firing together: for PoW exactly the number of salvos, of course.
Column 5 -- Which "question", please ? 55, 93 and 157 are the reported values from the ships.
Column 6 -- McMullen calls them "total guns able to fired". Guns that should have been fired in the ideal situation of no lost shot due to failures.
Column 7 -- Not exactly. It's = (column4 - 1) / column3 * 60 (please see my explanation here
viewtopic.php?f=1&t=8491&start=165#p82455)
Column 8 -- It's = (column7)*(1 - column9/100)) as effective salvos must take into account the output loss due to failures (column9). They represent the equivalent number of "perfect" (no failure) salvos fired by PoW / minute.
Column 9 -- Agree (column9 should be presented before column8 but I have used McMullen's format).
Column 10 -- It does apply to PoW (in case all guns are bearing, as per column description).
Column 11 -- Not exactly. It's column8 * column10. Represents the # of shells PoW could deliver to Bismarck (with all guns bearing) / minute.
Column 12 -- Agree
Regarding hitting or not, as you yourself said, all the other parameters (hit rate, range acquisition, effectiveness of hits, etc.) depends also on luck and/or on tactical decisions that nothing have to do with gunnery efficiency: a ship can straddle 4 times without hitting and another (with identical guns) can straddle only once, but hitting the enemy. Also, a hit can make "superficial damage" only or result in a catastrophic explosion.
Bye, Alberto
