Anyone have a clue how to find out what my ship power transfer rate is?

I have an engineering item that give me +2.2 PTR but i don't know what mine is, so i have no clue how good this is.

I mean if my PTR is 1000 then adding 2.2 will do almost nothing.

If it is 100 it still seems weak.

if it is 10 then that is a nice 20% boost.

If it is 1 that that would be a 200% increase and really be sweet.

So, anyone have a clue?
