The 3 was degraded, but that shouldn't change the EPC as there are still checkers on the 6pt to fill the potential gap. Any checker more than 2 on the deuce adds +1 eff pip. So we have 9.5 + 0.5 + 1 = 11 pips wastage for an EPC of about 66."

This is a very nice analysis. It makes sense and I agree completely. Thank you!

Why not add, say, 2 or 1 or 2.5 to the EPC? How do we assess the extra wastage?

Given the EPC, what is your formula for double/redouble/take decisions, please?
