thanks for showing Y3 failure in the GAR, I have missed it.
I see you still insist to compare apples with pears.
Rodney had to cease fire 7 times, KGV never wooded all her turrets together. Rodney course was much much complicated than KGV course (more stable), Rodney had (by design) a lower RoF, as logical mounting more heavy guns. Also KGV was closing to Bismarck in the final stages of the battle, Rodney was closer but KGV should have augmented her salvo rate as well (I think Tovey himself asked to close in order to put more shells on her) but you want to ignore this.
However I give up here, we can agree to disagree. My best estimate is 680 to 700 ordered shots for KGV, based on Y4 gun 49 fired shells, without firing for 25 (or 28) minutes, is yours still 550 now ?
Rodney fired for 3 minutes longer than KGV and that plus her greater turret traverse rate more than cancelled out any loss of output from her turns.* Additionally Rodney's gun crews could use any salvo delays to load guns and perform maintenance but there is no evidence from her salvo chart that the turns caused any noticeable loss of output. Rodney was, on average, closer to Bismarck and had better position for visibility given the weather and salvo smoke. RN RoF was based upon salvo firing and Rodney's theoretical maximum salvo rate was 3 salvos/min yet Rodney did not come close to this during the action and instead her RoF was set by the need to spot FoS which was made difficult by the Force 8 gale and commensurate sea state . KGV had the advantage of radar ranging (for a while) and more modern FC but Rodney had the advantage in turret traverse rates, closer average ranges and better visibility.
I pointed out that KGV did use broadside fire for part of the last half of the battle and this did raise the RoF of Y turret making it unrepresentative of the average salvo rate.
*Rodney's AFCT broke down at 0947 at salvo 90. Her average salvo rate for 60mins was therefore 1.5 per minute. ( BWOC, KGV's salvo rate was between 1.44 and 1.56 for the first 32 minutes which is virtually identical. ) Given one salvo every 40 seconds, Rodney could turn 160degs between salvos with no loss of output. A turn of 180 degrees would only result in 5 seconds delay.
