High Tech Explosives and Fantasy materials.

High tech gives calculations for pretty much any use of explosives that your player may come up with, beyond simply figuring out the damage dice. Blowing holes in walls, destroying timers, etc. But it gives these calculations versus wood, stone/concrete, and steel, what if you're chracters have happened across some Adamant (Which is 3 times stronger than stone), or Essential Metal (Which is three times stronger than bronze).

Using the base explosives damage calculation as an example, I find that a player would need nine times the weight for three times the damage. Does this work for the more precise explosives calculations that high tech sets out for demolitions?
