I do not beleive this to be accurate. Normal Gurps explosion damage is not proportional to mass of exposives in a linear fashion. There's a square function in there.

So uisng normal RAW if 1 lb of TNT does 6Dx2 or 42pts on average then 2500 lbs does the square root of 2500 x (6D x2). That should be about 50x as much of an average of 2100 pts.

So a 2100 hp explosion in a vacuum at 1 yard reduces by 2500x or round down to 0 pts damage at 50 yards and not 42hp.

Replacing the normal square function in calculations of Gurps ex damage with a cube would affect the starting number of dice and not how it reduced over distance..
