Live cube numbers assume maximum cube efficiency on this cube and ALL SUBSEQUENT CUBES. That does NOT translate to meaning that you can never have a take where your win less. The live cube take point in the position below in a money game would be 20% as it is in all positions where there are no gammons possible, but it is still trivially an optional take. At the score posted, the live cube takepoint for white is 18.99%on the RK MET, but the calculation of the live take point for white ATS starts from looking at blue's take point on a 32 cube and works back from there, which has no relevance whosoever since blue is already looking at a pass on any eight cube.
