Left dominant vs. Right dominant circulation of the heart

Can someone pleeeaase tell me what territories the LCX supplies in a left dominant circulation?

My best guess is this:

Usually people are right dominant, so the RCA supplies (the RV, the inferior LV AND the posterior LV / septum, as it gives off the PDA.

When people are left dominant, the LCX take over the posterior septum / LV, but leaves the inferior wall to the RCA...

Am I about right or is there more to it?

Thanks

Elliot
