Telesar "Computerized" Bulk Film Loader

I just recieved my new Telesar Computerized bulk film loader. This model has a counter for the frames loaded onto the roll and the number of feet remaining on the big roll. My question is: should there be a felt light trap? If not does anyone know how many frames at the end get exposed. This is why I tend to not use my Watson loader as it looses the last few frames and I have know idea when shooting if I am on the already exposed part of the film. The Loyd is much better this way, and I had hoped from looking at the Telesar loader it would be the same design.

With the Watson turn off the lights. Tape the spool to the tape. Assemble the can and close the loader. Turn the lights back on. Now when you load the film no exposed film. It's a pain. But if you really want to not waste a few frames then it'll work.
