Just done mine too LHR-EDU-MIA-DFW-LHR and had a great time in Florida. All in all great fun!
Remember the segment you qualify and become PLAT will be doubled as well so I got extra 4500 with the longest segment of my trip - well chuffed. Status got updated 3 days later. Waiting for my DBEQM to be posted now.
Have fun mate.
