Jasper gunnery report alone is not contradictory at all, and IMO is more than enough to build a sufficiently precise salvo chart.
My proposed one incorporates all the details given by Jasper. Of course, if you want to fit your "facts" (like open fire at 5:54, or Hood explosion at 5:58:50), you will never be able to build a realistic one, respecting Jasper.
The list of the most severe errors in you post:
you wrote: "He fired the 8th salvo at PoW just as PoW appeared to turn toward the KM ships (IE to avoid the sinking Hood) about 4 minutes after opening fire on PoW."
Why 4 minutes ? In my salvo chart, based on Jasper report and not on PG battlemap, they are 2 minutes (switch fire at 5:58:14, 8th salvo at 6:00:14).
you wrote: "He fired the 28th and last salvo under forward director control 770 seconds or 12:50 after opening fire. "
No, after 6,5 minutes after switching fire, or 9,5 minutes after open fire. Salvos are counted from switch fire as at long discussed in the thread viewtopic.php?f=1&t=5752&start=360
. Please take the time to read at least from pag.25 till 29.....
you wrote: "We have PE firing 3 salvos at Hood"
No, 5 salvos to Hood : have you read Jasper (and the above thread) or not ?
You need to put together the RoF, the expended shells (157) and the ordered ones (184), all clear facts, and build a salvo by salvo chart that fits your theory, and, for your own admission
, you are not able to do so starting from your assumptions, because
Stay to Jasper report and you will see that there is no contradiction in it
you find that: "...The information that does exist for PE via the Ktb is contradictory and/or at least not agreed upon..."
In the same way, when establishing PoW salvo chart you take McMullen, not Leach narrative.
If you look at McMullen salvo plot (PoW turn away started at 6:01:30 and thus ordered at 6:01) you may say it is "contradictory" with Leach narrative (CP hit at 6:02 and turn away ordered after that time), but we know very well
who is right among them.....
