Anyhow, in a week or so the BT adjustment algorithm will change, and it will become virtually impossible to play games with it.

Hi, could you please clarify why the new adjustment algorithm makes grinding impossible? The only improvement I see is that BT is not adjusted every block. It is adjusted every 2 blocks, so indeed an improvement, but not really impossible I think. Most probably I don't understand something. Thanks.
As kushti observed just above, in the current situation the forger may delay a block a little to influence the BT adjustment. Since currently the BT can change a lot (two times!) in just one step, every possibility to play with it can be considered a danger. With the new algorithm delaying one block makes a very small effect on the BT, because of the averaging.
