Normally anybody can see results you put into HalSail as soon as you enter them, provided they have the correct public link. So if you have a link on your club web site anybody who clicks it will see the results, even if you are still in the process of entering them. They might see that a particular boat has won a race, for instance, when in fact there are other boats with slower handicaps that you have not entered yet and that might win.
If this is a problem, you can embargo results until you are ready to release them. The available embargo periods are
The embargo only applies to people viewing the results without logging in.
You set the embargo policy at the series level. So when you make a new series, or edit an existing series, you have the option to set the embargo policy.
If a race in a series is embargoed, the public still have access to the results of earlier races in that series, if any. Public results for that series will look as though the embargoed race and any subsequent races have not yet been sailed.
