That never does the stable any harm heading into the yearling sales in 10 days but Purdon says it doesn't make the job of assessing his juveniles' chances any easier tonight.
He has three favoured runners in the male Young Guns heat and rates South Beach Arden (1) at around the same stage as big-money purchase Mach Shard (5). "They are both slightly ahead of the other horses and I really can't split them but the draws suggest South Beach Arden might be the better chance."
Purdon's two-year-old fillies are split two each in the fillies heats of the Young Guns and the master rates Bounty Lady (R6, No.6) as perhaps the most advanced. "She has won her trial and done it well but the other three were good at the workouts last weekend too. But she is the best chance of the fillies this week."
With so many winning chances, including Circles (race one) and Quevert (race three) it is a little surprising Purdon, who never likes labelling one stable rep above another, rates maiden Lareto a major chance against race winners in the Nevele R Fillies heat.
"She is a nice filly who went well last start and has some speed so has to be a good chance with any luck."
Tonight's meeting throws up some tricky puzzles for punters, none more so than race three where the better trotters like Prime Power, Blackguard's Corner, Quevert and Foray face hefty handicaps over 2200m.
"When I looked at the distance and saw it was 2200m I thought we might be off 30m but 40m makes it really tough," says Prime Power's trainer Todd Mitchell.
"He has been stepping well so hopefully we can get past a few early."
Race eight is similar, with some handy horses drawn well on the front meaning the better-performed Stroke Of Luck and Prince Of Pops could struggle from the second line in what could be a 2:40 or even faster 2200m.
Meanwhile, there are no concerns with Lazarus's draw when the wonder pacer tackles the A$200,000 Chariots of Fire in Sydney tomorrow night but the race still presents come challenges.
Not only does he faces a 1:49.2 miler in Salty Robyn but Sydney is forecast for 40C-plus tomorrow, hardly ideal for any New Zealand-trained horse.
Trainer Mark Purdon is happy barrier four gives him options but Lazarus punters will be hoping the hard fortnight and travel from Melbourne to Sydney this week haven't dulled the NZ Cup winner.
