I use this same print file page and have come up with a fix that works for me. I start cutting from the last frame- be it 36, 37 or 38. Cut my strips of 5 till I get to the beginning of the roll- then I cut that last strip to the same length as a five frame strip- note my roll number on the blank area and place this into a page reserved for 'tails' when that page is full it gets proofed. The original roll number gives me a reference to any notes on the film, but the page of tails gets it's own number in the negative book.
