PlaneShift terminology isn't exempt from the reality of language. When I use the term statistics to refer to the stats of my character, meaning all the statistics including those of skills, then that's the sense I am using statistics, and I am right in doing so. When you use the term stats to refer to body and mental stats (except for body development and empathy, which you consider to be skills and not stats), then you are right in doing so - although you leave yourself open to being misunderstood unless you explain yourself.
