But that could all be undone if rain forecast this weekend arrives, as although Probabeel has a good winning strike rate on soft tracks she simply isn't as potent on them.
"We are really hoping the weather stays better than predicted," says trainer Jamie Richards.
"So far it hasn't been bad but it could really change things."
Not only would a wet track blunt Probabeel's brilliance but could take away the advantage of an inside barrier draw and softer surfaces often help the Europeans.
Weather aside, Richards couldn't be happier. "I feel like wrapping her in cotton wool and putting her away for 24 hours because she is ready and I just don't want anything to go wrong."
So can the weight-for-age newcomer win the great race?
"It is hard to see you are going to win a Cox Plate but we have a happy, healthy in-form horse so I think she has an each-way chance," he says.
The forecast rain has seen Probabeel drift from $7 to $8 but still sits on the fourth line of betting for the 2040m thriller.
