Totally random update, here's a tool:

Its a web page with a bunch of simulations. It does the probability of numbers of 10s for rolling dice, likelyhood of having to keep 10s (or 1s) by the roll, perils of the warp chances, a sim that figures 3 ways to do critical damage, and warp travel.

Generally each rolls a million or hundred thousand tests and then spits out results, although the warp travel ones only do fifty thousand trials.

I'm also working on the andriod app again. There's a flaw in the "roll two times" code that doubles it (so 4 rolls instead of 2), and I'm adding quick buttons & an option to use the original tables from the book.

Thinking of maybe doing a spelljammer layered shields tab or a whole 'jammer stats tab. Unsure.
