OK ... first of all, I am sorry if I don't know enough about Flash photography because I hate reading the manual for 540.
I recently tried to shoot a fashion show and I was using K10D with the 540. It was a disaster and I was almost in tears when people walked up to me in the end asking for the photos. View:

First of all, I need to understand the concepts in plain simple english. Here is my question:
I keep Flash at P-TTL mounted on camera, shoot in Av mode and move flash exposure up or down on the body (info -> flash -> thumbwheel). But the flash does not recycle fast even with new batteries. It was taking 7-10seconds while models passed me by. I don't know what is P-TTL or TTL.
That night, I played with the flash a bit more in a pitch dark room. I got the flash into A mode and then say that you could change ISO and aperture on the flash after hitting the S button. I believe I moved the ISO on flash upto 1600 and aperture to a setting where I could shoot a fair distance (as per the feet scale on the bottom). Then setting the camera to burst mode (shot-after-shot), I was able to shoot photos quickly. Also, pausing for a 1 minute after 10 consecutive shots the camera didn't resume quickly. In fact, I think it changed back to P-TTL by itself or maybe I touched something.
What is the logic here?
Am I supposed to match the ISO/Av on the body to that on the flash? What works best for fast shooting?
Thanks in advance,
