> it just depends on the dog, on the day..
Also as in my case you have a very bouncy youngster, and they need more than one class just to settle.
My Veteran Jozi is a classic example.
The day she won her first CC at our club championship show she was a nightmare in Junior, had to re start her movement several times as she wanted to rush off etc.
She was forgiven this due to her age, and won the class, but I expect when it came to the challenge she would still have been OTT and not in contention.
As it was she went better in special Yearling, better again in Graduate, really settled in Post Graduate, and after a long rest was fine in special beginners one of the last classes before the challenge.
Also having won 5 classes and beaten another couple of class winners there were far fewer exhibits in the challenge so it was quicker, and the judge had fewer dogs to concentrate on :)
Now she is a veteran of 9 3/4 it is a nightmare showing as she is so OTT, she usually blows it completely in the breed classes, as she did yesterday only managing 4th, but is much better in stakes (bigger ring and more dogs helps a lot), she won the Veteran stakes yesterday.
Her granddaughter is similar and really needs to be settled before she will show at her best, so again for her 2 or 3 classes quickly followed by the challenge is ideal, also at last few shows it has also meant there were only 3 in the challenge.
Another reason for entering a higher class is to see how well your dog may fare against stiffer competition before they have to go up a class.
