Mark, the idea here is to shift the average.  Negative DL's
represent easier tasks, the more negative the DL, the easier
the task.  You don't GET to pick the lowest, you HAVE to
pick the lowest.

Ask and ye shall receive - I worked up the following table:

        DL       8-      9-      10-     11-     12-

        -4     .6613   .7746   .8601   .9205   .9586  
        -3     .5583   .6794   .7792   .8565   .9107
        -2     .4552   .5841   .6983   .7924   .8627
        -1     .3573   .4796   .5992   .7087   .8017
         0     .2593   .3750   .5000   .6250   .7407
        +1     .1821   .2751   .3847   .5043   .6265
        +2     .1049   .1752   .2693   .3835   .5123
        +3     .0732   .1274   .2046   .3045   .4255
        +4     .0414   .0795   .1399   .2254   .3387

ie, if I have an adjusted DX of 11 and I am attempting a
task which has a DL of +1, my odds of success are .5043.

Keep in mind that this system is not restricted to combat,
remember Henochius?  (For those of you who don't recall, 
check the example of play in ITL)  I don't recall the exact
circumstances, but Henochius made a 6D6 roll vs IQ ... and
his IQ was 8.  Under this system, that would equate to a 
DL of +3, his odds of success are .0732.  (Much better than
trying to roll an 8 or less on 6 dice!  For those of you
who don't want to work that out, the odds of success are
.0006)

I hope this helps.

Dan
