I was seeing the good tutorial of Emperor Cow where about the strikes he explain, like already noticed on the site some time ago, that the info on screen of every attack' start-up must be increased of 2 frames (the imput frame and the frame of impact)
So I was asking if this "rule" must be considered also for the frame traps (the tutorial don't mention it, but I wanted be sure): after a +4 advantage on block, the video showns like a following attack with an 11 start-up is able to create a 7 frame trap. But actually the frame trap is of 9 (or 8) frames?
