Deckman...
I notice the 16'X16' shed floor shows support boards 1'4" OC when using heavy-duty plywood vs. 2' OC when using standard plywood, which appears counterintuitive. I would have expected larger support-board spacing for heavy-duty plywood vs. standard 3/4" plywood for decking. Am I reading this wrong? Thnx.

The plywood is all the same. The heavy duty plans have more support boards to be able to take more load, that is the reason for the support boards to be closer.
