Off for a well earned rest the next couple of weeks so will try to leave you with some losers.
These are not one out lays but more than likely the horse that will be the worst way in my books.

B7 9 Wonderful Lass

M2 3 Prussian Officer
M3 7 Maquina
M6 6 Eraset
M7 3 Elusive King
4 Bellissimo
M8 6 General Truce

S2 2 Othello
3 Hard Liquor
S5 4 Shawnee Girl

Add to the list any horse in the market that opens longer than it's Prepost price.

G'Day Mark, any particular Pre-post there?

I ask because I find great differences both with opening prices and Pre-post prices, eg.

MR1-1 Betchoice op.= 7 1st fluc =6 IAS Op 5.5 1st Fluc = 6.5 (the only firmer and the winner if you used Betchoice)

MR1-8 Betchoice op 3.8 1st Fluc =4 (no bet if you used Betchoice ) BUT

IAS op 4.8 1st Fluc = 3.8, so a firmer (the opposite) if you used IAS

Party, party, party, you know I use the Courier Mail and Betchoice (the official openers !!!).

Anyways let's look at the 10 listed. Just the one winner @ 5.4 (BF SP).

You can tell the carnival's over, the money is thin, the SP's are rubbish and the bots have taken over again. A good time for a break.

ah, yes Courier Mail, yes I now use Betchoice as well, though I also still use IAS not as an opener but treat it AS a pre-post price.

Anyway you were spot on with your "losers" (winners)
I had a couple of disasters early on but almost got it back with cracker of a place bet on PR10-1 best tote
