Pre-qualifying could come down to draw to the button

So here's a scenario that the CCA  Curling Canada -- or any curling fan -- probably doesn't want to see. But it's possible a team could be eliminated from the pre-qualifier by a draw to the button. 

So far, Yukon defeated PEI and lost to Nova Scotia. The Bluenosers beat Yukon. If PEI defeated Nova Scotia in the game this afternoon, then the there will be a circular tie. The tiebreaker? The pre-game draws to the button. 

Prior to each game a member of the team throws an in-turn and and out-turn with the combined distance to the button being recorded. Here's what's happened so far. 

Game 1

Yk 20.8

PEI 25.1

Game 2

Yk 97.5

NS 23.7

So Yukon's total is pretty high. It has to hope that Nova Scotia beats PEI, in which case Nova Scotia and Yukon go to the final. If PEI wins, it has to hope that one of the two messes up its draws to the button. 

The top two teams will move on to the final to be played on Saturday.
