So it seems there is some weird crossover for JoL. With that said some fights you neglected to cast judge on cd, fix that, but on some logs it shows times where your JoL isn't used at all and the tanks is, and vice versa.

First graph is you. Second graph tank. You can clearly see where your JoL didn't anything and his did and vice versa. The next two graphs are your judge casts and his, and the final is an overview of JoL healing, if you click on your name and his on that graph you will see the crossover where which JoL healed and when.
I could have used another fight, but they were relatively the same. Consistancy here is gonna be off a little because normal fights do very little damage and you might even waste entire JoL stacks. Heroic or higher will probably give the best outcome with your JoL being used completely.
EDIT: As the above seems to be true for odyn and guarm where normal mode damage might be a little lackluster and bursty where you will get little out of JoL. Helya shows JoL doing much better and the tank AND your JoL are being used to a good extent. Helya damage in phase one is a little more constant and realistic in using JoL procs instead of burst heals capping hp out immediately on other fights and stopping the stacks from being used. You had many more casts of Judge than compared to guarm above as well.
