The stage play is overstressed sometimes, methinks.
Yes, I think so, too.
On the other hand, I think we can assume that they were taking into account all the external info they had available, such as cabin reports, ts and ps etc, and even then, with a quick performance review (accepting the overweight landing, as 1100kgs or so of fuel won't make that much difference) and setting up the arrival, and PIOSEE, DODAR or whatever, it's surprising how quick that 30 minutes goes.
And also, they know very well that the decisions made in that 30 minutes will be deconstructed at leisure over the next several weeks by the company. It's all very understandable.
