If you are solo carrying games to top 3 and getting tons of kills/dmg or going in 1v3 and downing 2 + taking the 3rd to 50health then why are people assuming that enemy squads are all "equally skilled", and only your teammates are the bad ones?
If 60 equally skilled people get into the same game then each of those players would get equally as many 15-20th place finishes as top 5 finishes.
@Wizardhawk There are plenty of different factors that effect that. For example your 3v1 comment.
If I'm sat on high ground with a longbow and your team comes charging through the open unaware of my location, i'll drop at least two of you with ease and by in an extremely good position to finish the third. However if we're both in that open ground the chances of me winning that fight drop significantly.
Being able to 3v1 is about more than skill that can be statistically tracked.
As for "equally skilled" lobbies, there's literally no such thing. It's based on skill ranges, so there will always be stronger and weaker teams in every lobby, even if the margin isn't by a great deal.
