Hi, I've been lurking for a while now and you all seem somewhat friendly, so hopefully you treat me kindly with what I presume is a newbie question.

From what I read, UK Racing release updates to horse's ratings at 7am each Tuesday morning. If a particular horse races Tuesday afternoon say, that performance is seemingly ignored when it comes to the handicapper apportioning weights for a race the horse speculatively entered for the coming Sunday. The Sunday handicapper does not have an updated rating to use as UK Racing has not calculated it yet. I've heard this circumstance referred to on William Hill Radio streams when a fresh horse performed well above expectations and that it's "beating the handicapper" by racing again quickly.

How does it work in Australia though? Racing NSW, for example, contracted an organisation that must provide updated ratings within 48 hours after race completion, yet I can look at a meeting in Port Macquarie 4 days from now and see the assigned weights in a Handicap. If a horse ran within the last 47.9 hours (i.e. up to 6 days out from the race) can that Port Macquarie weight get altered any time up until the gates open? Or are weights "locked in" at a certain time from the race/day of the week?

Cheers
