I recently did some shooting with my D100. It was set to JPEG (fine), Large files. The counter started at 75. So, I went about my day shooting... Some shots at Bushkill Falls and fireworks that night. Afterwards the counter said I had 31 shots left. I thought I had taken more than just 44 shots. So I downloaded. Low and behold, Nikon View 5.1.1 said I had taken 86 shots. I thought this only happened while using NEF compressed.
I take it the camera bases its count down on memory remaining, or am I wrong?

Like Victor said, the file size varies depending on how well the camera can compress the image. This leaves means it has to estimate how many more will fit. If you shoot with the lens cap on you'll be surprised how many shots you can get on a card
As a side note, I've seen some instances when shooint uncompressed raw the camera will say the card is full, then after it finishes clearing the buffer it says there's another shot available. Seems it slightly over-esimates the size of the raw files.

In case there's still confusion, jpeg compression will vary by the complexity of an image. A simple image with large areas of simple colors and shapes can be jpeg compressed much more than one that has a lot of detail.
The remedial math thing is common to all digital cameras, all of them have to estimate the number of shots by dividing the space by an engineer's idea of a good estimated file size.

I couldn't figure out why the D100 would get the estimate for uncompressed RAW files wrong some times, allowing an extra image to be stored. Turns out in the RAW file there's a 160x100 pixel JPEG so the file sizes vary slightly.
