Hadn't noticed it before, but your explanation makes sense. The Bend parms are opposite on both hands, and the limits are not symmetrical. For instance, On Misaki's left Index 1, Min -61 Max +33 On Misaki's right Index 1, Min -33 Max +61 So if the hand-pose switcher starts with a right hand value of 50, then negates it to -50, then (mistakenly) applies the 'old' min of -33 instead of the 'new' min of -61, the bend will be too small.
