As I said to Paddy, have a look at Post 153 on Page 16 of this thread. Then hopefully you should be right

Yes, anybody that's in the comp can pick an entirely new stable if they wish. This stable must be posted on here by Midnight Friday Apr 22 OR by Midnight the day before your next horse runs. For example, if you want to include a horse in your stable that's running tomorrow, then you have to post your stable by Midnight tonight.

You don't have to change your stable if you don't want to. You can leave it exactly how it is if you like. Just tell me you're keeping it the same and you can start using it the following day. Anybody that hasn't posted a new stable by Midnight Friday Apr 22, will simply continue using their original one from Saturday Apr 23.

Our betting weeks go from Saturday to Friday. Starting from Apr 29, you can change your stable every Friday. If you have a stable runner on Friday, you have to wait until after it's run to change your stable. Otherwise any time on Friday up till the cutoff time of Midnight.
