Yes except that you will not always find 200k and you will spend roughly 100k searching and on spells (if you use any). So therefor the average is 500k per hour. DUH! ;)
Yes you may occasionally get lucky and find that village with 300k+, but you may also be unlucky and spend 100k before you find a village with more than 150k coins available. So again the AVERAGE is roughly 500k per hour.... DUH! :p
