Under no circumstance will I aknowledge that someone with half my celerity can outrun me if we're in same condition.
That makes absolutely no sense.
Besides, forming some sort of a unified system is incredibly redundant. When you roleplay with good roleplayers, a solution as to what the diceroll will look like and what will it affect is reached very, very easily. In situations where it will prove to be necesary to roleplay with the not so good roleplayers and you'll have a hard time agreeing on a decent result without using the supplied combat system, you can refer to a third party. (or just not bother RPing with them, da?)

As for pure stat comparison, in my opinion and the way I've been doing it since I can remember, dice rolling is only relevant if the scores are apart at best at ten points.

To summarize, no, unless Dev gets around to implementing rolls that check againts stats mechanicaly without revealing them, it should always remain at discresion of those that are roleplaying together.
