Hey John, very interesting.
Any chance you could just clarify a couple of things regarding this formula;
Sectional density - I presume this is in lbs / sqin?
L ratio - is this in caliber lengths or physical length?
Hi Juan. Thanks.
Yep, secden is shell weight/diam^2. L ratio is in calibers, so you have to convert your shell ballistic length into its caliber basis.
I'm curious about the choice of some of these variables - a lot of them are more directly related to ballistic accuracy rather than firecontrol accuracy, so I'm left wondering if this is deliberate.
Yes it is. One must start somewhere and I thought the tube/round combo was a good place to begin. If ya put a stake in the ground it's good that everything bats from the same box. These thingies are 'devices' and I thought it appropriate to treat them as such. So made an algorithm to treat the 'devices'. The game code doesn't have any way of representing fire control, except as a "chunky" update to Allied capability in certain "years". Very unfortunate, but that's how the stock executable works.
Also - just from some back of the envelope math (waiting on answers to the above units before I mess with it too seriously), it seems like some weapons might be a little undervalued by this approach. In particular, the British 15in/42 which had some of the best dispersion characteristics of any large caliber gun in the war seems to be victim.
Well, yes, perhaps they are. The algorithm is just a basis to get everyone in the same box. It doesn't (can't) allow for the skill of the batter. As you know very well, there's tubes and then there's tubes; and every once in a while somebody gets a tube and a shell design together that hits the sweet spot (and sometimes, it's an utter roach). The algorithm simply provides a consistent and reproducable starting point for individual weapon adaptations. I tweak the algorithm, myself, for those weapons I am familiar with. Folks like yourself, that know other weapons can (and should) do the same. The algorithm is not cast in stone, it's a self-consistent starting point from where folks can depart without wondering "what do I do with this crap, Batman."
Would really appreciate hearing your thoughts (and if you're willing to share that spreadsheet).
All I have is yours, my friend. I'm finalizing a PI scenario for porting into AE but soon as that's done, I'll complete the spreadsheet (right now, only Japan and a third of US is done). Btw, it has the complete algorithm as column math and has not a few individual devices manually adjusted, in red.
