Brother, they are the same rating with zekken sporting way higher ADR, ACS, FK/FD ratio, etc on a far higher sample size. Zekken also outperformed Less on both of their match-ups against each other. There is no way that Less is "a mile away" from zekken; they're on the same level.
edit: Forgot to mention zekken even trolled two maps (vs. G2). Without those the rating would have been something like 1.20.
