I was reading through Arch Graphic Stds and came across a table that says 2x yellow pine deck boards can span up to 5′. Seems like a bit far. What do you usually span?

There's a constant source of clean water for you to use, and all you have to do is collect it.

It all depends on the load range required. A deck under the drip line of a steel roof in heavyu snow country might need to be designed for an 80# load. Most decks need about 50 - 60#. Some in the deep south are comfortable with 25 IF it is no more than three feet above ground. Note that we read every year about a campus party on the deck that gives way and kills somebody. Human flesh is heavy.
I think you might be reading your table wrong. I can remember lots of roof decks in the south sheathed with 2x6 T&G @5' or 6' OC where the required load rating was only about 15# Can't imagine framing a walkon deck that way though.
