Choose a 2 player game (rather than a 4 player game) to speed things up (a 2nd controller would be best and set the AI players to zero) Try to score with all your pawns and when it's player 2's turn just nudge the stick up and right slowly so their pawn doesn't even get on the board. After you've both had your 4 turns, press Y to automatically move your counters up the board. Repeat until all your counters are home, trying not to waste any time between turns and you should get this easily.
