See how happy you are when that option is taken off the table.
I doubt extension of stay based on retirement will ever be "taken off the table", since It is a major "earner" for immigration.
Here is an extract from the online 90 day report user manual which says wait for "about" 3 days for the immigration officer to check and approve your report.

I'm currently watching season 2 of The Capture on BBC iPlayer. Season 2 is even better than season 1 IMHO. Definitely worth a look. iPlayer has all episodes from seasons 1 & 2.
