[Runequest] Critical Range/Resolution

[Lev Lafayette]

nota bene: Changed subject to actual topic.

Whilst I agree a 10% of skill range is a neat and easy, I'm sticking to
a 'high end' (critical failure) 'low end' (critical success) range.
There is another slight problem (very slight) with the doubles system
expressed which goes beyond my personal aesthetics.

Consider for example, a character who has 50% ability, surely not
uncommon at all. In an extremes 10% critical range they have a 5% chance
of critical success (01-05) and a 10% chance of critical failure
(96-00). In a doubles system however they only have a 4% chance of a
critical success (11, 22, 33, 44) and a 6% chance of critical failure
(55, 66, 77, 88, 99, 00).

HTH,


Lev
