videotape circulation

Does anyone have figures on the durability of VHS tape, esp. how many
times a cassette can circulate before drop-outs, degradation, etc. make
it unwatchable?

In my case, the setting is a public library with heavy video
circulation. The tapes are stored upright, but not always rewound after
use. Many of the tapes are over ten years old. Some have circulated
300+ times.

Thanks...
