Sky Sports have been innovtaive in all its sporting developments over the past 20 years, but I can't see this one lasting.
After 30 minutes tonight, the new 'Margin Meter' predicted that Widnes would win by 12 points. Wakefield then run out winners by 18 points.  

 Classic. I hope someone hasn't spent their mortgage on developing it.  
 
 
Most Rugby League games ebb and flow and mid game you'd normally have more chance on pinning the tail on a donkey, than you would devising some mathematic formula to forecast the final result. 
I wouldn't be surprised if Wakefield's winning run lasts longer than the 'Margin Meter'!
