swinging requires sequenced release of accumulators #2 then #3 per tgm. that requires a 10-18-B wrist action. The left wrist is bent for a 10-18-B wrist action. 10-18-A, which maintains a flat left wrist, seems to require symultaneous release to stay on plane, other than with a Zero accumulator #3, how can #2 accumulator be released on plane with a flat left wrist?
