700K? If you lost one offensive village per attack, you would not be able to rebuild your losses fast enough.
A little story Lagmonster, I went one on one with a n00b on w1 (that was almost exactly my size)...but a n00b with static defense a few months ago. After a week, I doubled my size, but had to rebuild all of my offense (except 1 village). The fight took about a week.
Based on that, you can double yourself in a week, take 2 weeks to rebuild and double again. That would get you to about 400K, not 800.
So, either, the villages had no defenses (as in pure offense) or you didn't do the clearing attacks. Well, finding 30 offense villages only would sound to be extremely lucky. So, perhaps, those villages were emptied on your behalf?
