Wado Ryu 2.0/Jiyu Kumite

In this new style/organization, we have a special rule set for jiyu kumite.

You can win in one of this ways:

opponent gives up (surrender by joint locks or for other reasons)
fighter is standing, while other fighter is on the floor fore more than one second
3 realistic and good hits to the (protected) head
3 realistic and good kicks
opponent unable to move (joint locks, etc) for more than 5 seconds

The fights are divided in to categorys by points:

Start with 5 points.
For each life year below 60 years you add 0.1 points.
For each life year above 60 years you substract 0.5 points
Each Dan is as many points as the number of the dan (2nd Dan is 2 points and so on)
each kilogram below 80 substracts 0.1 points, over 80 kilogram nothing added or substracted.

For example:

Fighter A is 90 kilos (+0 pts), 20 years old (+4 pts) and 1st Dan (+1 pt). Total 5 points.
Fighter B is 80 kilos (+0 pts), 30 years old (+3 pts), 2nd Dan (+2 pts). Total 5 points.
Fighter C is 100 kilos (+0 pts), 40 years old (+2 pt), 2nd Dan (+2 pts). Total 4 points.
Fighter D is 80 kilos (+0 pts), 60 years old (+0 pts), 6th Dan (+6 pts). Total 6 points.
Fighter E is 60 kilogram (-2 pts), 65 years old (-2.5 pts) and 1st Kyu (0 pts). Total -4.5 points.
Fighter F is 100 kilogram (+0 pts), 30 years old (+3 pts) and 5th Dan (+5 pts). Total 8 points.
Fighter F is 100 kilogram (+0 pts), 70 years old (-5 pts) and 8th Dan (+8 pts). Total 3 points.

A and B can fight each other, because one person is heavyer, but has a lower dan-level, so it is about equal.

10 points is the Maximum.
