I've got 480 kills because I was 1 hitting most EGs for the first couple days, if I did a better job of checking in every 30 mins I'd be well over 500, and I haven't used any puddings. Eventually when you get really high SED, and if you get the slayers, you can clear a freaking TON of EGs. Sometimes I spend 1$ a day on the Event Gacha ticket...although I'm sitting at 30 Event Gacha tickets right now so that's not even necessary.
