As I said ‘for example’ since I didn’t or wouldnt really bother researching it.
It’s not smufs that gain that much - its new accounts that gain - or lose that same amount in x comp games after they finish placements. Sure there is preformance based rewards until diamond, but it takes away as much as it gives to smurfs, and its capped at 10ish extra SR if I remember correctly.
Regarding this comment and previous one - taking common logic into account its more likely that low SR accounts will quit before high ranking ones, therefore it’s likely that high ranked accounts will spend more time in game before quiting, just due to skill grind if anything else.
The only point here still stands - that SR is innacurate display of someones skill. And thing like MMR just contributes to more innacuracy because a mere computer algorythm can never anticipate if player queuing will be in a good mood or bad one (from being tilted to dog dying and what not reasons).
Starting with myself as an example - out of last 30 games, there were maybe 3 balanced ones, rest were either destroying or being destroyed - complimenting to my argument that current SR system is terrible and innacurate in displaying someones skill.
