Kevin,
The internal actuations counter cannot be altered as far as I know.
The file counter can and is easy to do, hence it is no good indicator at all of the camera usage.
For photo ME (

Be sure to understand that in the quality assurance process of the Pentax factory the camera's shutter is used as well.
All camera's new in shop have a shutter counter > 0.
Most of them have a shutter counter around 250 or so, new out of the box.
Cheers, Bert
