Oh yes, those Ex/Cx scores that don't mean a damn thing in practical terms - another waste of space. (Apparently there's something in T4, but how that's supposed to be applied consistently in the T5SS and and why it's not described in T5 either is beyond me).
You're avoiding my question, Don. How many vehicles/guns/ships are in T5 that have been arbitrarily designed rather than designed using their Maker systems?
And it's not really about mapping it to a distribution, it's about wasting space on a worldgen system that is just ignored when designing published sectors, and that's just another wasted opportunity to fix things in T5. Again, how many of the fixes that you're applying are actually in T5's worldgen system? If you're adjusting world size to allow breathable atmospheres, does the T5 worldgen do the same to avoid those tiny cannonball worlds with breathable atmospheres? Or does it still generate habitable moon-sized planets with breathable atmospheres? Heck, are trade and worldgen systems in T5 even consistent with eachother?
None - there's no vehicles list in T5 that has specifications.
(There are prices in the ship design sequence for the standard designs, giving tonnages and prices, but not designed out statistics. And that list is a holdover from CT.)
