My thought when making the thread. If you attend a rules seminar, they will explain that one of the IBJJF's goals is to emulate a real-life self-defense situation. So they reward with points, because in a street fight, you would be more likely to submit your opponent, strike your opponent and finish the fight from an advantageous position like side control, back control, or mount. This is one of the reasons they use a “progressive” approach to scoring.
If this is the case, why do we need to reward people for passing the guard, but not so for simply establishing side control? If I suplex someone and land in side control, I'm only awarded 2 points for the throw. I am not awarded 3 points, because I landed in side control and didn't pass the guard.
If someone is on top of me in side control, and I physically reverse the position, landing in top side control, I'm not awarded any points for a sweep or for attaining side control, because I never passed their guard, and I never used my guard to reverse the position.
What difference does it make how I get to side control, if I can just as easily end the confrontation from the position? If you're trying to emulate a self-defense situation, who cares if I threw the guy and landed in side, or if I used an intricate pass to get there? I'm still in the same position and can just as easily finish.
