Jim.I don't know about all S600's but I know for sure that my first one Johnnydeerhunter built me that i will have 2 pics before getting past it.
I have another S600 that is clicking them off about every 5 to 7 seconds between flashes.This one surprised me.Now this is with newly charged batteries too.I can tell by the pic times that the lower the batteries get the longer it takes to build up for the next flash.
The wakeup time does take longer than some commercial cams but there is no comparision after that.
There is so much I don't know about the homebrews or how it is done.I know there is a Fast hack and settings to some of the boards that make them faster too.
I am soon going to be finding out how the XLP boards are.They are suppose to be pic taking machines.
