Nactations of 43S-22N-65 — 2012 Update

[In case there are other nactators besides myself rummaging around among these old BGO posts, I have this update for the Nactations of 43S-22N-65.] Sometime in late 2010 or early 2011, Nack refined the definition of R (Run) thusly:
An R play is not only confined to the far side, but one of the destinations needs to be in the 17pt to 13pt range (not 18pt to 13pt). A move with both (or all) checkers played to the 18pt or further back is in the U/V family.
Under this defintion, we can update the Nactations given in the preceding post:
43S-22N-65
43S-22N-65Z
43S-22N-65R
The play on the bottom left is assigned to the Z (Reverse split) family because it moves the 5 on the far side (20/15), and moves the 6 down (15/9). Incidentally, 43S-22N-65r is now 24/18 20/15. Mike
