No, one leg kick doesn’t equal one takedown.
Again I posted the criteria above it is about being effective and also the proportion of the round that takes place in that zone.
Lets start with striking. If in the exchanges I hit you and you just take it, I am winning the striking. If I hit you and you counter, we are even, if I throw, you counter but I then recounter, I am winning. Obviously we have to take into account how effective the punches are. One big solid punch that rocks you backwards would score more than a bunch of probing jabs that you are just walking through.
For the grappling, I am looking for the person who is using grappling to actively improve their position and look for a way to end the fight, sweeps, sub attempts that have to be actively defended, working to pass the guard and obtain mount etc.
Next comes control (and this is normally where the takedowns come in unless they are big slams which would be included in the previous areas) who is controlling where the fight takes place? Is one fighter taking the other down at will to an advantageous position? Is one fighter ragdolling the other round the ring. Is one totally pinning and tieing up the other fighter on the ground? Conversly is one fighter sprawling like a motherfucker and keeping it standing so they can use their better striking?
If I can’t separate them on anything else it will come down to aggerssion, who is looking to win the round? Who is actually throwing.
The way that I actually keep score is to keep a mental tally (like counting cards in blackjack.) The fighters start the round at 10 - 10. One fighter has come out strong and is landing strikes so my mental ticker has switched to 10 - 9 in their favour. Second fighter takes the first down and starts dropping elbows in the guard (back to 10 - 10), fighter on the bottom sweeps gets to mount lands some gnp of their own (10 - 9 again).
The second the round ends I write down the tally score that was in my head before there is a chance for the crowd or one particular remembered punch or whatever to cloud my score. That paper goes to the ref to be handed to the head judge (which is actually me for the promotion I work for) and I clear my mind ready for the next round. Starting again, 10 - 10 with no bias based on previous rounds.
I actually make a point of not reading the scores from the other judges during the fight because I don’t want their scores to bias me.
End of the fight, I pull all the papers out of my back pocket, add them up and give the outcome to the ring announcer.
If the fight ends inside the distance I have to get the time from the timekeeper and give the official decision on what the technique was that ended the fight to the announcer.
