How Does Elo Work With Groups?
#1

Anyways, my question is... How does ELO work with the matchmaker when you're in a group? Say, a group of 4. For the sake of discussion, let's say two of the four are very skilled high-ELO players, and the other two are very low-ELO, perhaps even new accounts.
What happens? Does the matchmaker average the ELO score of all four and try to place the group into a match with similar scores to the average? Or does it simply pick the highest of the four and go from there? Or... ??? I'm assuming nobody actually knows for certain, but any hints or insight would be nice.
I ask because of the outcome of a recent match I was in, of which I have a screenshot of the rather... Surprising after-match scoreboard. I don't want to post it at the moment, for fear of it turning into a "name and shame", but I also didn't want to send it in as a bug/exploit report, in case there's not actually anything wrong, and I'm just a noob. >.>

Sometimes I've seen two groups of 4 matched against groups of 3, 3, and 2. You can tell when this happens because the 8-player system only splits groups up in 3, 3, and 2 for actual 3 man premades with 2 pugs or 2 random players.
Smaller groups tend to be pit against completely random pugs or other smaller groups, but as a group of 2 you'll never find yourself against 4 groups of 2 on the other side. It never happens.
When you group up with someone higher, it becomes an average of the scores and your opponents will be tougher.
Myself I like to group up with two or three newer players, as it brings my ELO average down a bit to where I see more trial builds. Our opponents are still tougher than the newer players might face alone, but they're not as tough as I would normally face when by myself. This lets me bring my stock builds and have more than just a chance.
Scores are usually not name and shame as long as you don't point out anyone specifically, but yes sometimes there are landslide victories. This can happen as a result of poor matching, or poor cooperation within the group.
Once it becomes 8 on 6, it'll very likely become a landslide. It's very important to protect each other and cooperate. Builds also need to be diverse, because of everyone brings a missile boat, who will protect them when the enemy gets close? If everyone brings a brawler, how will you get close if you can't divert attention away from you? If everyone is a sniper, what happens when everyone becomes too hot? And if they're all lights, what happens when the other side camps at the base?
But again to clearly answer, it'll bleed the numbers into an average. This is why sometimes one player will do exceedingly well despite not having a cheese build; he's from a much higher ELO and got 'bled in' by an average to offset his or her team's lower average compared to the enemy, or because he or she was part of a group of much lower players.

honestly I think it just snatches the first 30 people looking for a match in whichever game mode, slaps the 2,3 or 4 man on one side, any other groups (after finding their averages) on the other side and then divides the leftovers based on their WLR/KDR and maybe "time played"
it then sloughs off the rest and voila, 16 people in a game.
this is why you can find a match very fast solo pugging in "Any" mode and also why it takes longer when you're in a skilled 4man trying to find assault only, cuz it's waiting for at least a closely skilled 4, 3 or 2-2mans to balance it out.
then I believe there is a timer, if by the end of that timer it can't match skills even remotely it a) fails to find a match or b ) just tosses in some poor brand spanking new players which results in what I call a "steamroll" (8-0 or 8-1 in about 5 minutes.)
but what do I know, i'm no mathematician or algorithmagician.

Step 1) Elo for each individual is listed.
Step 2) Elo is totaled.
Step 3) Elo Total is written on a slip of paper.
Step 4) All pieces of paper are thrown into a bowl and covered with banana slices.
Step 5) The bowl is given to a room full of monkeys, who then eat the bananas and slips of paper.
Step 6) The monkeys poop. The poo is searched through, and slips of paper that end up in the same pile have their players square off against each other.

I've been seeing a lot of this too. Mainly when I pug but occasionally when I drop with a 4 man. I've been seeing new players in trial mech on both sides too, which I find rather odd.

Just because a match becomes an 8-0 does not mean the teams were uneven and it does not mean the Elo was broken.
Once a team is down a couple of players, the remaining 8 vs 6 can very easily turn into a complete rout, even between even teams. You can see this happen for yourself when playing scrims within your own merc corp: Two teams of 8 playing multiple matches with each other in a session, and some of those matches will still be 8-0! Tactics and chance play a big part, and a single tactical error can cause a wipe among otherwise equal teams.

True, and as I mentioned, there have been some noob issues lately...

You need to keep in mind its picking from players who've clicked Launch inside a roughly 30 second window. Even with tens of thousands playing, that's a fairly small pool.
The further you are from average, too, the more likely you are to see more random matches. This is because Elo scores, by the nature of the system, conform to a bell curve. There's always going to be exponentially more average players than exceptionally good or bad ones. Hence "average".
This means you're only likely to get high team average elo scores during very busy times; otherwise there just aren't going to get enough exceptional elo players clicking launch inside the window.

I had one with five "one shot" kills in the height of the poptarting craze - not because I was cheating or amazingly good, but just because I got absurdly lucky. Sure felt awesome though.
