Since most tour players have no idea about accumulators, I would tend to think they are talking about their perception of effort. They use a variety of accumulators around the green, but probably think about the club staying low to the ground rather than zeroing # 3 and minimizing #2. Or whatever.

When they talk about 100%, their feet tend to come off the ground. Think wide open, barely reachable par five.
