Does you vvinning or losing affect your champion score ?

I vvas just vvondering this because I vvent 31/4/3 as Tankgot in 3v3 TT. My Fiddlesticks had a bit of a kill to death, not that good, but he vvas trying and diffidently, and our Katrina, she had 0/22 and vvas constantly putting a vote to surrender. Even vvhen me, or Fiddlesticks and i killed their entire team. All except Brand, the only one vvho could challenge me. He had 33/4/2 and had a lovver cs, but full magic damage. I had 4,000+ health, 150+ armor, and a high magic resist. (I forgot hovv much.) I killed their team, except Brand, five to six times. I had only died four times in half an hour, and both of his teammates knevv to run. My Kass, she kept on running face first into Brand and his team. Fiddlesticks vvas farming top, vvhile I vvas killing their Rakan. VVhen the game vvas done, after getting 33 kills, getting the highest damage on my team, and taking thousands of points of damage. I didn't get S rank. After only dying four times. I even got a killstreak of 17, firstblood, and the first tovver kill !

IF YOU VVANT TO SKIP THE ABOVE TEXT : I did vvell, 33/4/3 did a load of damage (65.3k), killed their team five to six times, and vvas only challenged by a full ap Brand. Because both my Kass vvas 0/22, vve lost and even though I did vvell, I did not get an S rank. I bring this up, because I've gone 22/4 and gotten S ranks on Urgot. So, do they affect the score ? And if so, vvhy ? If a person goes completely insane, yet one or tvvo people on their team either feeds, or somehovv causes a loss, should they not get the same rank as if they vvon ?

If you have an opinion on the topic, please comment, I vvould like to discuss.

Also, my "VV" button is broken, so I use double "v"'s.
