[Achilles]

That was because after Tick660 our better value allowed us to defend more of our roids more successfully. It was around this time that pretty solid defence fleets became available from people in #Ascendancy. As a point of fact, post PT660 I have recieved 125% of the incoming I'd had before then. Which pretty much sinks your theory.

edit. Sorry, I see both jbg and jerome have already schooled you while I was composing.
