How accurate is the automated line thing for pip review whilst waiting for the letter?

I received the text my pip review was complete on Wednesday morning just after 8am, so I assume it was complete the day before.

I’ve done the thing of calling the automated line as my anxiety can’t settle, it’s tells me my next Patel my is due in the 17th as it was meant to be and is the normal amount I’d receive.

What I’m anxious about and my Ind the answer to is; is the automated line updated immediately, ie the moment the decision is made (so Tuesday afternoon/weds morning) or does that take a little bit to get updated and I may as well just anxious keep waiting for the letter to arrive?

So yeah simply put; just how reliable ai calling the automated line to check on the outcome of review in this way? Tia
