So a friend and I ran the code after converting into Ruby. I was working on getting a random number generator in Fortran. Still am... Lulz. The reason why is because I was curious to know what the overall chance was to a near perfect degree. However, the percents in the table you listed are halved for some reason in some of the rows. Row one is fine, but 5 isn't.
In terms of making percent chances and all, we found, which your numbers reflect that your best odds when using a scroll are to either +/- 2 or 3. Then followed by +/- 1,4 and 0, and then 5's being the least common to happen.
After running 1 million tries of the chaos script, these are the actual percent values for the change in ONE stat.
So the chance of going -5 in one stat is 1.5744% in, the chance of the stat not changing is 3.127%, etc. -5 > 0 > 5 is the order of the table. Of course, these are Experimental Values. I wouldn't write these in stone.
Of course I could run a simulation on a full item and get the total chance results and see how it behaves. But that is kinda silly. If you got total changes in all things, most likely its going to be in the +2,3 - 2,3 range. Which makes sense.
