try aflock and aelock, inspiration from http://chdk.wikia.com/wiki/HDR_Fast_Shooter
trying the less reliable method, couldn't get prev to shoot more than once
whoo! an improvement
let's see if aflock and aelock have any gains
holy shit this is getting good!
maybe disabling the lcd also helps?
Even lower! seems set_disable_lcd is the wrong way to go, will have to check other methods. need to try and disable sounds from script too
