My hypothesuspicion (do you like that Portmanteau?) I do and it just hit me as I was typing lol!

I believe it is due to the combined efforts of yourself, beaker and Jedo.

Thanks to you guys, I personally deactivated a lot of plots that were underperforming and drastically increased my Efficiency!

However... this means my "active" plots dropped from like 28 to 9 (10 now?)

This is probably happening across the Regions and why it's a Zero Sum equation at the moment.

Nothing more than extrapolation of data from you, my personal experience and the community reaction to your efforts.
