First off nice work TS.
Second it is actually retarded and indefensible to calculate finishes without counting losses.
Every single fight entered has a range of outcomes. You can finish or not. If you do not finish that fight that counts against you.
Here is how absurd your statistic gets and why it is worthless.
Tony WildCard Ferguson is the most successful finisher in the history of the sport of MMA by your stat as he finished 100% of his wins. While others can tie him, no one can be a better finisher.
So according to your stat what is this amazing Anthony WildCard Fergusons record?
He is 2 wins and 16 losses with both wins via finish for a 100% finish rate.
Now to demonstrate how retarded your view is if you had another fighter who fought the same 18 opponents winning all 18 fights, 9 via finish and 9 via decision he would have a 50% finish rate. Worse then WildCard. WTF?
When fighters say "I finish fights" they mean just that. Give them a fight and they are likely to finish it. To calculate how good a fighter is at finishing fights you need to calculate it as a percent of ALL fights.
Thus Wildcards finish rate is 2 of 18 fights or 11%. He is a low end finisher. ANd fighter B is a 50% finisher and substantially better then Anthony. Done the correct way the stats tell you that. Done your way, the wrong way, we have no choice but to accept WIldcard as a far better finisher then Anderson SIlva and maybe Anderson should go train with him to learn how to finish at a higher rate.
