When I got home I double checked and I still had 75 pics left with 507 taken. I have shot the card to empty before and got exactly 386 so why now is it getting 582?
Like others have said many unpredictable variables are in play there, making forecast accuracy not only averaged-based, but largely dynamic too, by necessity.
On top of that, at any given calc, or recalc instance; the camera should also err on the conservative side, else we owners would be cursing for being robbed when stated expectations are not reasonably delivered.
So when you work out how long that proverbial piece of string
really is, then knowing the exact capacity of a memory card in image-storage units, will itself no longer be an enigma either.
On thinking about it, along with calculations being done based on the camera's full configuration state at a given time, there's also the implied issues of filesystem space block-units and fragmentation, temp file write~deletions, or in-cam combination activity, like HDR, etc. etc., to contend.
Marvelous what these gadgets get up to these days... innit.
But surely there are greater things to ponder, so I'll go back to watching my toenails grow now.
