The only time that KO and pillz remaining are taken into account in the ELO room is when there is a Daily Tourney on-going. And even with that, it would only affect the battle points earned, not the ELO points earned.
If you are only after the Daily Tourneys, I suggest you switch from ELO to another room. Players in ELO naturally plays slower, the timer there is longer as well. Aside from that, it is well documented that some people leave their battles in that room.
On a related note:
Is it considered bad courtesy to leave an ELO match? For example, if the game ends on the first turn (eg. I overpill egregiously etc.), is it courteous to stay the game, or to resign (as you might in chess)?
