Shooto scoring?

Just got the rules for C Class of JD today and i'm a bit confused (which happens easliy). It says "the 2 sub-referees shall judge striking points as follows 10:10 no difference down to 10:6 overwhelming difference". The says "the referee shall judge grappling points as follows: takedown 2 points if you gain position 1 point if dont gain position. Positioning 5 points back mount, 4 points mount and 2 points side control"

What i'm confussed about is how does the ref or judges combine the stand up bit and the grappling bit???

anyone?

What about in Spartan or XFC how do they combine stand up fighting and ground fighting points at the end of the round?
