Question for KEM farmers

With my multiplier around 700% and the collider on I get about 1 level per 10 KEMs.
I'm already 939 though. So I think it's more EXP needed to "level"

I'm level 440ish, multiplier is just over 260% (+ all SH buildings) and I always have collider turned on. I build 25 at a time (so I stop when the price tops out at $14400 per building). I level up roughly 3 times per cycle and do this around 3 times a day... so 9 donuts per day.... + I go up a level pretty much every time I clear buildings/characters every 4 hours which pays for my KEM farm....so maybe 10-12 donuts per day + any extras. I seem to comfortably average 70+ per week including collecting donuts from daily tasks, railyard etc.

I only started KEM farming about 4-6 weeks ago and have go gone up about 320 levels in that time! Wish I started sooner!

levels or bonut boxes? levels occur twice as fast as bonut boxes! i've got a muultiplier of 565% and it takes roughly 11-12 KEM per bonut box. I ussually do 3-4 rounds of approx 30-40 KEM, so i get usually 4-5 bonut boxes per 4 hours, so approx 15 donuts per 4 hours, so approx 50-60 donuts a day.

Levels. I'm still only at Level 352.
I was just curious because I started the XP Collider 9 days ago without buying & selling KEMs so I wanted to compare. My multiplier is 387.4 plus the hidden from all Heights buildings.
I really wish I'd thought to write down what level I was on when I started the thing...

Even with a fairly low multiplier, KEM farming is effective. I have a multiplier of 128 (was 120 when I started the collider less than 8 days ago) + hidden multiplier. I am averaging 10 levels a day.

You can read my log of KEM farming at the end of this thread:

I'm on level 200-something. I place 23 KEM every 4 hours and get somewhere north of 550,000xp from them, so along with character/building xp I average 5 levels a day, or 50 donuts over the course of a 10 day collider for a 25 donut profit (ignoring regular level ups, which to be fair is probably only about 1 in ten days anyway).

KEM farming really comes into it's own at level 939 as whilst the requirements to level are doubled, you can get up to triple the donuts!

Exactly what @jellypawn said.

I just posted​ some details about fun after lvl 939 in the 2000 club thread if you're interested.

Very true, but it takes a long time to get there. There is no reason to wait when almost anybody would get a profit from farming.
