Actually, that's the complete opposite of my point. Collision damage is
falling damage. You collide with the ground. They should be the same thing (or result in very similar damages), but they aren't (and they don't):

(If the two objects collide at a speed of less than 5" per turn, any resulting damage is purely cosmetic.) Objects do their own Armor Value in damage, times the Damage Multiplier.
Note that an object's Mass number has little to do with it's AV. A diamond with a mass of 1 might have an AV of (say) 2d10+2. If you hurl a diamond at the ground at a height of 10" such that it reaches the ground at the end of the turn:
By 4.3.5, that's 1*1d6*(10/2.26) = 4.41*1d6 damage to whatever it lands on, and it takes that same amount of damage itself (between 4 and 26 damage)
By 4.3.6, it's (2d10+2)*2 = 2*(2d10)+4 damage to what it lands on (between 6 and 44), and the damage it takes will depend on the AV of whatever was landed on my period.
You could similarly take a large ball of wadded-up tissue paper (AV 1d6 or less, also mass 1). It does the same exact damage as a diamond by 4.3.5, but by 4.3.6, you get 2*(1d6)+4 (between 6 and 16).
Basically, you could arbitrarily choose the damage type, and have the result differ greatly.
It doesn't really matter all that much, honestly. It's a discrepancy, and if you're an anorak enough to sneakily choose the damage type that's more beneficial to you, well, screw you. But for the sake of perfection, those rules ought to be in line with each other, and they're not. I think the rulebook is sort of littered with small issues like that, and most of them aren't worth the bother of fixing. But if (as Pitlogg was suggesting) you want a rulebook that's 5x larger, you could straighten out some of the idiosyncrasies and make a fully detailed and consistent system for brik physix.
