[AusRace] Calculating deductions from payouts in cases of horses scratched at the barrier

[chiron1 at iinet.net.au]

	Greetings ausracers. Long time no post. Was looking through recent
postings 

	in the archive a few days ago. Ausrace is still collectively the
best pool of knowledge 

	on all things racing. Have a question for the mathematically
inclined, if anyone can help.

	Had a small successful punt at Belmont today which had to be
reduced from the 

	face value because there was a scratching at the barrier. 

	The scratched horse (St Bel) was at approx. $11.5/12.0win  when it
was withdrawn 

	(shortly before start time). 

	 

	My bet was with an on-course bookie and had a face value of $100
exactly (place bet). Post race the 

	winning horse WITH BOOKIES, was paid out less 8c in $1 for win and
less 11c in $1 for place; 

	2nd horse was paid less 11c in $1 for place and 3rd horse less 14c in
$1 for place.... as said, ONLY 

	WITH ON COURSE BOOKIES.

	 

	Why the variation in rate for the 3rd place? 

	 

	The TAB fixed odds service which I think is provided by William Hill,
paid less 8c win for the winner

	and less 8c place for all 3 placegetters. 

	 

	The fixed odds TAB prices (win and place) were very similar to the
on course bookies' market.... literally only 

	very small SP variations.  The answer is probably staring me in the
face but I can't see why the place deduction 

	rate is variable instead of fixed for all 3 place dividends ala the
TAB fixed odds figure.

	 

	The 3 placegetters were (memory) at PLACE ODDS of $2.50, $2.70,
$5.00 PRIOR to the scratching.

	 

	Anyone? 

	Regards, Tony
