The longest possible Spec 7 game is 30 points. 28 for the main
game and 2 for the playoffs.
The starting sequence you gave is one way to get to the longest
possible game. If I break it down to where the end of each line
here represents a PGP, then one way to reach the longest game
would be:
111111
888
444
7
723
...
It's almost cheating if you have your own rotation board to play
with, so I won't give the answer for max PGP. Except to say that
it is not 11.
