This just happened to me a few moments ago:
[Roll result: 83 (open d100: 38)]
An ethereal guardswoman feints to the left, and you almost buy the ruse, but you recover just in time.
Roundtime: 2 sec.
.
I have skill in Feint (know 3 ranks) and also Cunning Defense (also know 3 ranks).
The result was BELOW 100. (Which is the threshold for success rolls in, uhhh... everything. Isn't it?)
By the text, I "almost buy the ruse."
.
Why the hell do I get RT for?!?!?
