A fastest ever run home time was posted at Wentworth Park on Thursday night but Flash Boom Bang's amazing but unofficial figures won't appear in the record books.
When Palawa King's trainer Jack Smith's dog gave his kennelmate Irinka Benji a big start on the back straight before snatching victory by a neck in a personal best 29.43, Flash Boom Bang ran home in record breaking figures of 11.26.
The previous best run home time is credited to Shakey Jakey, who won a maiden race over 520m at Wentworth Park in April, 2014, in 29.07, getting to the line in 11.33.
After Friday's power-packed win by Flash Boom Bang, Smith was asked when he was going to test the dog over 720m.
Could he have another Palawa King on his hands?
Surprisingly, Smith doubts Flash Boom Bang can become a top class long-distance performer.
"Flash Boom Bang will go over a middle distance later on but I doubt he will become a true stayer.
"After running home in 11.26 on Thursday, I have to wonder how he could possibly maintain that finishing rate for another 200 metres.
"If he is able to do that Flash Boom Bang will be a hell of a stayer, but it's hard to imagine him going that fast for 720m.''
Before Thursday's race Smith was asked whether he was cheering for Irinka Benji or Flash Boom Bang in their 520m fifth grade, and the genial Forbes mentor quipped: "Benji, because I own him!''
But Smith was happy to share Flash Boom Bang's $3975 first prizemoney with the dog's owner, his great mate Brian Jaggers.
Flash Boom Bang's field sense on Thursday also impressed his trainer, as after being seventh away from box six, the dog stayed in the centre of the track when he made a charge at the first turn, threading his way into third position on the back straight.
While many at Wentworth Park on Thursday must have been salivating at the prospect of Flash Boom Bang going over a middle distance, a greyhound's strong finish at the end of 520m does not always equate to a career over 600 to 700m.
As a rookie journalist I was in awe of William Anthony, trained by the legendary Bob Doak, who was a greyhound renowned for his last-to-first performances over 580 yards (530m) at Wenty.
When William Anthony made his debut over 675 yards (617m) at Bulli, I hurried down Bulli Pass and plonked my week's pay on Doak's dog.
I was feeling pretty chuffed when he ran six lengths in front at the half-way mark, but William Anthony stopped to a walk near the finish and was beaten by the strong finishing Golden Deb.
William Anthony was apparently suited up to 625 yards, but then hit a brick wall when another 50 yards (46m) was a head of him, and was never again tried beyond sprint distances.
Meanwhile what trainer Jack Smith described as a "sore leg" prevented Palawa King adding to his $1.1 million in earnings at The Meadows on Saturday night.
Palawa King, who was set to go into Saturday's Fireball final with 31 wins and 26 placings from 72 starts, is not expected to be sidelined for any length of time.
