Personal Progression

My main is my Hunter.  I like raiding with him but for my guild I am sometimes needed in other roles.  Last week we got a new boss down and I was tanking.  This leaves my Hunter behind in progression.

Would I consider my personal progression to include all my characters, just the one I am currently on, or my main? 

I've done things on other characters I have not done on my main.  I've done stuff on my main I have not done on other characters.

For me, none of my characters will look very progressed on their own but when you add up their body of experience this expansion it looks much better.

So for me, is my personal progression everyone combined, or is it whomever I am on at the time?
