How many runs will a 16mm copy last?

A good loop can last all night or 3 minutes. The projector itself, the quality of the splice(s), the quality of the sprocket holes, the length of the film loop, what has been done to it and where are all factors.
In the last couple of years I have moved away from running loops -and into other film-less projector art areas- as I find it very high maintenance and limiting. My one-of-a-kind loops get mangled fast and once the film is chewed up, it is gone. Good luck with your project.

They had a Japanese projector, a quick shifter, which hacks into the perforation. So I offered a better construction, a Siemens & Halske 2000. A looping device on top of the projector conceived by a Frenchman was left there and the film threaded straight through it. Nobody would see that there was only a three-foot length laced up. This time I had access to a polyester-base positive.
I joined the ends with pressure-sensitive transparent tape, lubricated the film and had it run at 24 fps for seven weeks, six days the week, from 10 a. m. to 5 p. m. The splice broke exactly three times (its purpose as protecting measure for the whole). No wear whatsoever on that sniplet after 211,680 (two-hundred-eleven-thousand-six-hundred-and-eighty) runs.
Of course, a longer copy will not last that much because of more dust collecting on it due to static charge. Scratches must be expected.
