Thing is though when a game snowballs into what most would call a stomp, those who move up to Tier 1 are doing well enough that even on bad losses, it is enough to make up for it and even more.
KDR means does not mean as much since getting a Kill could be generated with 1pt of damage. KMDD/Solo kills would be more appropriate but even though it does not show if you were 2nd place on 0 or 9 kills. This is likely why damage is the largest factor.
Jarl's list though is incomplete since it is calculated since the Seasons went live in June 2016 a year and half ago. PSR went live in August 2015.
Found it. I had remarked about moving into Tier 1 on 11-19-2016. When PSR was seeded from the previous Elo system in 8-19-2015 I was Tier 3.6ish mark. I may be a good team player but I am definitely not an elite player.

Anyhow, just looking at a couple of the long time tier 4-5 players, many have a 9.0+ W/L, KDR 0.7 but an overall MS of less than 160MS or less with the exception of the last 3 seasons generating 200-260 MS while noting he were able to break into Tier 4 from Tier 5.
As for being an experience bar, in other games you can be killing light blue NPC and gain very little experience (you also are doing less damage) vs killing dark blues/yellows, more experience but also you have to put out more damage to do so. Unlike those type of damages though, a player spends about the same amount of time looking for a game, in combat and putting out damage. A loss without putting out enough damage/etc for a higher MS is similar to dying and either not getting a rez at all or getting a lower percentage rez, not earning all of the experience points lost.
