I copy-pasted your program and got similar results. However I
increased the dice size to 100 then 1000 and it gets worse (but
still under 10%).
As another poster, I think the gaussian distribution is what we all
"naturally" expect for random events. I don't think however
introducing a bias will make any good.
A random suit is by nature not predictable but statistically. If you
know, given a low percentage of success, that after a success you'll
never have another success, it is predictable, it is no longer
random. That's "why" you have sometimes suits of success : "for" you
not to be able to predict the result. To contradictate your
assumptions.
Indeed, if you know that, you'll be able to screw the carefully
chosen percentages. For example by switching to a serie of quick,
low-cost tests after you got a success on a long, high-cost
one. Designers will soon have to go through math courses to assigned
any percentage of success to a given skill, just to get the same
number of successes per unit of time that was initially
designed. And players will have very various overall successes/time
depending of the method they are using. This introduce a serious
design problem.
Also, if you choose the bias method, you have to keep the state for
every player, every mob, maybe even every skills per player, wich
may become a serious dev problem as well.
That's not the case with a gaussian distrib however. I think
gaussian may be the solution. The designers have to well understand
the implications however. For example the fact that doubling a skill
level doesn't always translate to a double chance of overcoming a
given difficulty. This may also cause another PR problem btw.
