It doesn't according to my experience. Did it in 800-1200 range using gob only and looked at break even resources count or better. This isn't that much different than high frequency barch or all archer collectors raids pre patch, except there were a lot more abandoned bases previously. And I was th9/10.
Do you next a lot? I only next up to 10 times at most as this is more about raid frequency.
The truth is, for th11 I see mostly th10 bases that has most resource buildings inside and the occasional th8-9 with nothing at all. I even see more maxed TH10 and full th11 than I see abandoned th9-10...
p.s., I got 725M GG, 710M EE, 2.5M HH, so I am not inexperienced in farming...
