A number of small observations.

Laying those horses is -10.90% after commission.
This reinforces the fact that although it should be neutral, Betfair favours backers in almost all areas.
Layers are pushing it up a hill.
Backers are starting off with an advantage and are further advantaged by market rules.
Layers start off disadvantaged and are further disadvantaged by market rules.

The TAB average for favourites is 33%, I would guess that the 1% is not a fluctuation, but rather better "picking".
Sometimes you see the inverse of first and second favourite on Betfair compared with bookies and tote.
I also think in the case of equal favourites, Betfair users are more decisive.
