Yup.
Lots of speculation about it on this thread.
I wonder if it's a complete tie.
I remember there was a tie in the dessert course when Spencer and someone else both got 40 and Andi had to make the final choice, but I'm not sure that there's been an overall tie.
As has been mentioned, I don't know what happens if one has won the canape and the other has won the pre-dessert, so they couldn't be used to resolve the problem.
Maybe Andi would have to adjudicate again?
Mere speculation on my part, though.
