I can't really say if it took longer... previous briskets were roasted in a pan in the oven without folding. On my last one (first smoked brisket) I took the narrowest portion and folded it up and over... so it was only +- 8" long portion folded over leaving its overall length at about the maximum I could fit on the grate.
It was an interesting brisket. I asked the butcher (at the grocery store) for a smallish packer cyrovac... He came up with a 6.x lbs brisket cyrovac... I could not easily discern a point versus flat. I think it was possibly a flat only... I assumed it would have a point and flat, but I knew they were typically 10 lbs+- . The part near the fold fell apart when slicing like a point would but I found no specific fat layer between a flat and point like normal. I cooked it about 10.5 hours to about an internal temp of 175 or so before pulling, wrapping, and resting in a towel laden cooler. Flavor was good, but I would like it more moist. This was not too unexpected as I cooked fat side down, no mopping, no wrapping in foil except for resting.
#2 I will follow closer to Jeff's latest newsletter... smoke until 150, wrap with foil, add broth, cook until 200... then finish up with some burnt ends on the grill.
