Ok, normally I don't handle the math, I usually let Basutai handle it. But in regards to Seal of Command Proc chance.

Proc chance per swing = __(Proc per minute)x(Weapon speed)__

                                       (60 seconds)

So, now that we have the formula...

Proc chance per swing = __[b](7)x(3.6)__

                                    **(60)**

Proc chance per swing = **0.42%.**

To factor in the new SoC Glyph, simply use the same equation but multiply the proc per minute by 120% first. (It equals 50.4% proc chance with Glyph)

Hope this helps.
