I've found this not to be the case.

A quick and dirty review of the last 102 horses that opened on track at less than $2.05 demonstrates.

Backing them all less 5% commission on Betfair resulted in a loss of 1.45 units.

Backing the drifters less 5% commission on Betfair resulted in a loss of 8.92 units.

Backing the firmers less 5% commission on Betfair resulted in a profit of 7.47 units.

If I expand the opening price to $3.00 or less, it becomes more interesting.

Backing them all less 5% commission on Betfair resulted in a profit of 22.09 units.

Backing the drifters less 5% commission on Betfair resulted in a profit of 12.21 units.

Backing the firmers less 5% commission on Betfair resulted in a profit of 9.88 units.

So based on the above information, backing the firmers at $2.00 or less opening price and all at $2.05 to $3.00 we get this...
$ 7.47
$23.54

$31.01 units profit from 398 bets, or 7.79% POT based simply on price.

This is from the last 7 Saturday meetings only.
