The following position is about as close a take as can be. The EPC for each side is 16.99. Use that as a clue to guess the take equity if the side on roll is adjusted instead to 010110 which makes the EPC .01 worse.

 White is Player 2 score: 0 pip: 11 Unlimited Game pip: 11 score: 0 Blue is Player 1
XGID=--AA--A------------a--aa--:0:0:1:00:0:0:0:0:10
Blue on roll, cube action?

Thus, what is double take equity here?
