Goodreads Developers discussion

The API terms page says, "[You agree to:] Not request any method more than once a second."

If I make one request per minute on average, but two requests happen to fall within a second of each other, is this a violation of the API terms?

I volunteer for a charity that sends donated books to needy children. I'm planning to use the Goodreads API to improve their inventory system. Several volunteers will be scanning books and there's a chance that two volunteers using separate computers could scan a book at the same time. Overall use of the API will be quite light.

As I understand - this limit is per application instance.
