Getting a Super Priority Appointment - ILR 5-year route as partner of Brit

We're gearing up for making my wife's application for ILR (5 year route) in Jan.

Just getting acquainted with the hell again after 2.5 years. 

I'm applying online and get to the point where it says to select a service and it's only offering "standard". We want to do the super priority service.

I've done a bit of research and from what I can tell, it'll be a case of preparing my wife's application as I have done in advance and then coming back on-line in the early hours in the hope that the super priority option is available (as they're only releasing a few a day). Have I got this right?

Like I said, we'll actually be applying in Jan, I just want to make sure I know what to do in advance...

That's correct - if it doesn't offer Super Priority at the time of submitting the application, then you just need to keep trying to see if it shows up at another time, as they only offer Super Priority to a certain number of applicants per day.

Hopefully other people who have had to do this recently will be able to shed some light on the best time of day try to get Super Priority.

I waited until midnight and tried again.  Apparently they release 60 super priority spots a day, 

Hi, same experience as LKK, we waited until about midnight about a month ago, and several popped up.
