No, I think the defrag sorted out the WEI files made it run better and do a better job on the SSD

Reason why defragging a SSD doesn't work is because the controller on your SSD tricks the OS to believe where certain parts of data are on the drive, but in reality the SSD controller is constantly moving stuff around behind the scenes but the OS has no clue about that. In our case (got the same drive like you've got) the sandforce controller is fooling the OS into thinking it's just a regular old sata drive on there with chunks of data scattered all over the platter.

There's no way a defrag program could really analyze where the data is because they can't get/look/analyze past that controller.

That extra .2 you gained was probably just a fluke, maybe something was writing to the SSD first time you ran the test resulting in a 7.3.

+ Wear lvling like others mentioned, defragging a SSD is bad mkay

The only reason I can think of why the score went up is maybe there were some blocks that weren't marked by TRIM. Perhaps these blocks used by WEI were then marked by TRIM when you defragged.

Still, defragmenting a SSD are unnecessary and wasteful.
