I don't see how a move in which not only the recipient, but person throwing it are usually SERIOUSLY injured is allowed in a league that people fight every 4 days in? It isn't just the UFC. Bellator, Stikeforce, Pride, etc all banned it I believe. Concussions, serious lacerations/brusing, cracked skulls, etc. How a body can recover from that or even the most minor injuries in 4 days is amazing to me. For example, if you blew the guys knee out, he will be out of commission for months. I've never heard of any league in the US allowing that, minus some backyard/bar fighting make-shift fight club. I know you've said before, it's mind over body or whatever, but how someone is expected to fight 4 days after a minor injury over and over is beyond me.
I can understand not waiting the preferred amount of time for weighing-in, because you'd literally have to maintain the same amount of weight in order to meet the requirements of 145 pounds every 4 days. Also, if you finished him with a liver shot, it was more than likely a TKO, not a KO,
Props for whatever league you compete in. It sounds like the craziest, most non-traditional mma league I've ever heard of. As someone who is very interested in learning about MMA, I find this thread extremely informative.
Also, since you hold a 145lbs belt, I'm assuming that implies that your league is at least semi-professional. If that's the case, you should inform whoever keeps MMA records, like the site listed below. With your 64th win, you rank 5th in the history of MMA in wins. Of all time.

I think you've also probably shattered the world record for most MMA fights in a year, by a lot:
