Well, I thought I was done with this thread...

My experiments show that the loss of film is not at the rear end, but at 
the leader.  I know this may sound like it makes no sense, but it does.

There has been some shortening of the rolls since years ago (I'd guess 
at most one frame), but not as much as is showing up in loss of frames 
in newer cameras (back to 36 or max 37).  What I see mainly is wasted 
leader due to too much of it being "used" during the autoload process. 
The autoload feature should actually allow for extra frames is anything. 
This, I believe, is an "agreement" with maybe both film manufacturers 
and labs.

The most slide boxes used by labs can no longer even fit 39 mounted 
frames anymore.
