Stats and Skill, numeric conversion


SLA has a scale of 1-10 for Skills and Stats for the Human range. The Stats for an average human are 5.

ORE has a scale of 1-5, for Skills and Stats. The Stats for an average human are 2.

A simple formula of dividing the SLA Stat by 2 and rounding down looks to be the answer. (5/2 = 2.5 rounded down to 2) This gives the baseline in both SLA and ORE to be equal, as well as the max and min.

I have an adverse reaction to the ORE baseline human stat due to the probability of success on an unskilled role. A die pool of 2d10 has a 10% chance of success without a difficulty. Apply the ORE unskilled difficulty of 4 to this and it drops to 7%.

Due to this, and my experience running Godlike with the baseline of 2, I am more comfortable with ORE using a baseline of 3 for stats. This allows for a 20% chance of success on an unskilled check, and a 50% on a skilled check (3 in stat, 1 in skill).

So, what formula to hit the baseline of 3 for the average person? Rounding up rather than down is one option, but there is also rounding down then adding one. Anyway, a table to show a few option. At the moment I am partial to the simple rounding up option.
