OTB, I thought the double was pretty clear, and was surprised to see the rollout verdict of ND/T. Blue's equity is over +0.8, White is on the bar, and has a home-board blot, but apparently there's not enough volatility to make this a technical double. Again I would be curious to see if XG's absolute equity numbers concur with GNU's.
