Determing the DC...

It has been some time since I have been able to post, but hopefully reality has slowed enough that I can now get back to it regularly...

Over at the new M20 Forums, it was suggested, when there were no rules for a given task, one could make a ruling by finding the character's minimum and maximum potential based on their total modifiers applied. For example; if a character had a total modifier of +5 (say from stats and skills) then the min possible would be 6 and the max would be 26. Splitting that in half (16?) would give an equivalent of a 50% chance of success, and halving that again would give you a 25% chance on the low end and a 75% on the high end of success/failure.

I understand that this may be a common practice, but I don't understand it. If you are going to do this, for a single character, what is the point of even factoring in modifiers? Why not just have them roll a d20 and read it as it lies? This may be more feasible/usable if you find the parties min/max, but YMMV and this is definitely IMHO.

I think I personally prefer a static 10, 15, 20, 25 DC. After all, a DC of 20 should be extremely difficult for your average character and a DC of 25 impossible without something helping them out.

Just rambling thoughts today...
