You would have to have a K factor. The more difficult maneuvers have to have the rewards of higher possible points. I just don't see judging a split ess the same as you would a cross box humpty bump with 1/4 rolls.
The purpose behind the K factor was to make our playing field equal against guys like Chip Hyde, Mike McConville, Hanno Prettner, etc.... against guys that can beat anyone with one eye closed and 2 hands tied behind their back.
We ought simply judge the manuever against that one particular maneuver. We cannot judge a split ess the same as a humpty bump or a loop. We judge the maneuver by itself on its own merits mintaining continuity. Keeping it simple, on a grading scale of 1-10 is important for me.
