How many flashes can I get on one set of 2500 mAh rechargeable Nimh batteries? At full power? At half power?

My manual gives an estimate of 190 flashes at full power. No info on half power. I'd guess add about a third. Anyone have first hand experience?

190? Seems kind of low... what kind of batteries is that based on?

That's for the Ni-MH. That's the second largest. Lithium provides 230. It's on Page F-21 of the manual.
(Edit to add: ) Scanned the page from my manual and sent via e-mail. Hope it's helpful.

I get a whole days worth, I use bounce most of the time. (as many as 400 photos)
Weddings, events (indoor and out door), and etc...
I am currently using, Energizer NiMh 2450maH and Duracell precharged 2000maH.
And NO I am not getting the over heat issue!

I should have specified, what the manual states is the MINIMUM flashes expected with a given battery configuration.

I, too, am not getting the overheat issue. I figured I'd chime in because this made me hesitant to get one initially. The only time I ran into that was when I was popping a whole bunch of continuous shots at full power when I was screwing around with lighting technique.
