Out of interest how does a screenshot show it was done in an hour?
I think this, along with most of the other earnings per hour, are an exaggeration. Yes it is possible to earn 30 million in a reasonable BH session, but that isn't one hour.
The fact is the maths just doesn't support getting that kind of return. You would need to be killing at a rate of about 100,000 credits per minute before any bonus and while this might be possible for a few minutes the spawn rate just won't support this over an hour.

We have BHers making 30+mil/hour (confirmed by screenshots, FYI),
