Injury Tolerance: Damage Reduction

:see also Damage Reduction (rule) in 3e
GURPS Powers 52 version of Injury Tolerance, also shorthanded as IT(DR) also found on MA45.
A Divisor of 5 is [125]; To price a divisor of 10 or more, find it (as yards) in the Linear Measurement column of the Size and Speed/Range Table, add 2 to the corresponding entry in the Size column, and multiply the sum by 25.Pg 115
So a Divisor of 1,000 is 1,000 yards which is +16; add the 2 and one gets 450 ((16+2)*25) points. Which means a Divisor of 3,000 works out to 525 ((19+2)*25) points.
Page 118 under the right column "Invulnerability" gives a Cosmic option for there not being a minimum of 1 damage.
The rules description there:
:Minimum injury from an attack that pierces DR is always 1 HP
Is a rephrasing of B379:
:the minimum injury is 1 HP for any attack that penetrates DR at all
==interaction with other forms of Injury Tolerance==
due to:
:after subtracting DR from damage and applying wounding modifiers
This would mean for example that ITDR could reduce the 2 damage maximum from Diffuse down to 1.
As to how it would treat 1:
==Cheapest version==
GURPS Sorcery: Protection and Warning Spells p 5:
:Injury Tolerance 1.5 has a base cost of 25 points, by induction.
==House rule==
Don't round, or round to a single decimal place, use Fractional Damage

:IMHO (and feel free to email Kromm to see if he agrees), fully Ablative DR is no longer "DR" and is more like "reduced-utility HP" to me, so I'd let it stack behind the IT(DR). But that would definitely be making an exception to the rule, as opposed to following the rules as written.
