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 ground for more than 3 seconds
3 realistic and good hits to the (protected) head
3 realistic and good kicks
fighter brings enemy to floor, while he keeps standing
opponent is exactly 60 seconds after begin of the fight unable to move (joint locks, etc)

The fights are divided in to categorys by points:

Start with 5 points.
For each year over 30 years, you substract 0.1 points.
Each Dan is as many points as the number of the dan (2nd Dan is 2 points and so on)
each kilogram below 100 substracts one point, over 100 kilogram nothing added or substracted.

For example:

Fighter A is 90 kilos (-1 pt), 20 years old (+0 pts) and 1st Dan (+1 pt). Total 5 points.
Fighter B is 80 kilos (-2 pts), 30 years old (+0 pts), 2nd Dan (+2 pts). Total 5 points.
Fighter C is 100 kilos (+0 pts), 40 years old (-1 pt), 2nd Dan (+2 pts). Total 6 points.
Fighter D is 80 kilos (-2 pts), 60 years old (-3 pts), 6th Dan (+6 pts). Total 6 points.
Fighter E is 40 kilogram (-4 pts), 80 years old (-5 pts) and 1st Kyu (0 pts). Total -4 points.
Fighter F is 100 kilogram (+0 pts), 30 years old (+0 pts) and 5th Dan (+5 pts). Total 10 points.
Fighter F is 100 kilogram (+0 pts), 80 years old (-5 pts) and 10th Dan (+10 pts). Total 10 points.

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

C and B can also fight each other. While D is much older, he has higher Dan, which means a lot of training years and to be very talented.

10 points is the Maximum.
