Brisket done already?

14.5 lbs whole prime packer put on at 11:45 last night,  265* on the flameboss.  It was 180* by 4am.  Checked it with my thermapen.  Now at 6am it's 195*.  The point is like butter, the flat needs a little more time.   I was planning on 10-12 hrs cook, to eat dinner around 3.  Its like there was no stall at all.

Trust your indications, especially the feel in the thick part of the flat.  If there, then it's finished.
Was the above weight, post-trim as you can easily remove 2.5-3 lbs of fat.  I don't run with a controller but if 265*F was your grate temp then that would likely translate to around 290*F on the dome.  So, under an hour/lb is totally to be expected.  Under 30-40 minutes a lb, not so much.  
But in the end game, "The friggin cow drives the cook!"  FWIW-

It was 15.87 lbs on the label trimmed to 14.5 lbs after trimming.  I weighed the trimmings and it was only 1 lbs 4 oz.  Which I thought I was light, just going by looks.  Maybe my scale is off.  The dome temp stayed right at about 280 thehole cook.  I let it go to 200* and pulled it.   The feel is there.   Its FTC for the next few hours till its time for burnt ends.
