So I was thinking about the concept of customizable spinal mounts and came to the following conclusion. Hasn't Dan already provided most of the mathematical tools to mod the spinal mounts? We already know how to calculate the SU and ORat of weapons based on their Range, To-Hit, ROF, PEN and DMG. Can't we just apply those to the spinal mount calculations to derive say a spinal mount that hits on a 4+ and has a PEN of 2?
The basic spinal mounts assume a range based on the size of the mounting hull. Can't we really change it to any range, as long as we modify the SU and ORat by a similar amount? The same with To-hit, ROF, PEN and DMG.
For example: To get a spinal mount that hits on a 4+ just divide the stock spinal mount SU by 0.67 and multiply it by 0.5 then divide the stock ORat by the old SU and multiply it by the new SU. Voila, a spinal that hits on a 4+
PEN and DMG are even easier because the stock spinal assumes that they are 1 (well, DMG is 1x HS). So to get higher PEN and DMG simply multiply the stock SU by the new PEN and/or DMG and as above divide the stock ORat by the old SU and multiply it by the new SU. Keep in mind that a HS 10 ship with a DMG 2 spinal mount would actually be doing 20 points of damage, at least until it took some internals.
ROF is trickier because all other weapons use ROF+1 in their calculations. So for a spinal mount to have a ROF of say 2, divide the stock SU by 2 and multiply it by ( new ROF+1 ). Again as above, divide the stock ORat by the old SU and multiply it by the new SU.
About Range though, I am not sure what to do. Range is already factored into the stock spinal mount's ORat but not the SU. Anyone have any ideas?
Does anyone see any glaring mathematic or balance issues with any of this?
