Too tired to type much. Here's the VASL Analyzer numbers:
Opponent: Snakes: 0. Boxcars 2. DR Average = 7.568
(37 rolls). dr Average = 4.25 (4 rolls)
scrub: Snakes: 2. Boxcars 0. DR
Average = 7.19 (42 rolls). dr Average = 1.75 (4 rolls)
DR was pretty even. But the boxcars and snakes tell the story. One dr meant an ambush... Great game, great and gracious opponent.
