So what was originally happening at 9:05 in Matt's statement is pushed forward to 8:55 (10 minutes).
if we were to take the extreme of the times 8:45* - 9:05** that is a 20 minute gap.
* 8:45 when DP says he left
** 9:05 at time Matt goes to do apartment check after the Paynes have been hurried up.
(I'm just using times you have already quoted).
In my opinion people changed their memories to fit in with each other. That's why I prefer the earlier statements which are relatively uncontaminated by discussion between the members of the group.
4th May
Kate and Gerry say nothing
Russell says the Paynes arrived at 8.50, Matthew checked just after 9.00
Matthew says the Paynes arrived at 9.00, he checked at 9.05.
Fiona and Dianne say they left their apartment at 8.45, no mention of Matthew.
Dave said they arrived at 8.55, no mention of Matthew.
Jane says Russell and the Paynes arrived at 9.00, no mention of Matthew.
Rachael says Matthew went to find the Paynes and they arrived at 9.00, followed by Matthew a few minutes later.
Seven people agree that they didn't arrive in time for their booking, they were late. They disagree on how late; was it fifteen minutes as in Russell's written timeline or 30 minutes as Matthew, Jane and Rachael say?
Two independent witnesses say no-one was all that late.
On the day of the disappearance, all were seated at the table between 20H35 and 20H45. He remembers them arriving as usual. Had they arrived late, this would have been noted by the staff.

http://www.mccannpjfiles.co.uk/PJ/STEPHEN-CARPENTER.htmIn the end it was Rachael's account which was adopted by the whole group, but why? Perhaps the answer lies in Jane's statement;
At about 21.00 her husband arrived at the restaurant, having got E**e to sleep. For this reason and because Fiona, David and Diane only arrived at about 21.00,
the dinner, reserved for 20.30, only began after 21.00.http://www.mccannpjfiles.co.uk/PJ/JANE-TANNER.htm
