It depends. A severe wrong edge is a -2 or -3 GOE and the final GOE awarded has to be negative.
A unclear edge takeoff is only a -1 or -2 GOE subtracted from any positive GOE earned on a jump/combo. The final GOE is not required to be negative for minor flutzes. In theory you could flutz a combo and earn +3 GOE before the deduction and still finish the jump with +2 GOE. I've looked at a lot of protocols this year and I've never seen any actual (e) call with a positive GOE. It should be noted that a flutz doesn't neccasarily even show up on the protocols. By that I mean the tech panel can call a flutz and not put an (e) on the scoresheet. So it's possible they call a 3ltz-3t but put (no sign) on the protocols and the jump earns +1 and no one knows any deduction happened but in fact it may have and that jump could have been a +2 since (no sign) calls are simply a -1 reduction to GOE and NOT required to be negative. (This confuses me to no end)
We can't forget that the final scores per element are an average of seven judges so you'll see flutzes often awarded -.30 or -.60 on the protocols. Factored by 7.

The third page here describes all deductions and which ones are required to have a negative GOE and the ones that can still be positive in the end.
I'm sorry I know you're a Julia fan, and this is the judges fault and not hers just to make it clear, but she was given a +1 by a certain judge on the 3lz-2t at sochi during her fs with an e call. But it seems an e call last season might also mean an unclear edge take off.. So confusing.
