GM tool to compute the difficulty of a Dungeon Fantasy RPG or GURPS fight by simplistically simulating multiple fights and putting bounds on the difficulty, e.g. "This encounter has roughly the combat power of 14-17 orcs or 3-4 peshkalis."
Every so often I'll meet a new GM who is just getting into Dungeon Fantasy or GURPS DF, and who is struggling to figure out how to "read" monster difficulty from stat blocks. I remember being one of those GMs not too long ago even. Unlike D&D, DFRPG stat blocks don't come labeled with a metric like "CR" to say how tough they are supposed to be relative to other monsters, and for an experienced GM that makes a lot of sense, since it really, really depends on tactics and details.
But for a new GM who isn't sure yet whether black puddings are stronger or weaker than slugbeasts, it might be nice to have some kind of a rating system.
D&D is simplistic enough that you can get a very, very rough metric by basically multiplying typical DPR x HP modified by AC. In DFRPG or GURPS you can't do that because of DR and the active defense rules, which make longevity highly nonlinear.
But! you can just run a cage fight with a bunch of orcs and measure a monster's approximate orcpower, or ogrepower, or peshkalipower.

It's not documented inside the app, but if you're on a PC you can use '<' and '>' and left/right/up/down arrow keys to navigate the fight log, and on the monster edit screen Ctrl+S and Escape work for OK and Cancel respectively.
