# (TFT) Re: H3 System Revisited: Skewing the Bell Curve

Such a system ignores a basic premise of reality: it is easier for
skilled characters to perform simple tasks and harder for unskilled
to perform more difficult ones.  The TFT system flies in the face of
that: no matter what your skill level, you are going to succeed or fail
5% of the time.

And it shows! This is pretty intricate.

I'm still at a bit of a loss here. For -DL's, the player "gets" to pick the lowest of a set of dice, but for +DL's, he "has" to pick the highest of the set?
```
```
I guess the other thing I'm missing, which I think I'd have to see to know whether I like it or not, is a table showing odds of a "normal" (ie not "automatic") hit or miss as a function of DX and DL. Ie I know that at adjDX 10, on 3 dice, I have a 50% chance of hitting, plus 5% of critical hit, plus 5% of catastrophic failure. Same (about) applies at DX 14 on 4 dice.
```
How does this system skew the odds of "normal" hits and misses?
