The LEED User guidance on this credit includes the following sentence:  "But just by switching things up a little you can still make this work, since you’re allowed to include up to five products from any one manufacturer."  I've checked the LEED NC v4 reference guide, and don't see any language limiting project teams to using no more than five products from one manufacturer.  There is a limitation that you need products from at least five different manufacturers, but nothing stating that you are limited to a certain number of products per manufacturer.  Was there an addendum addressing this that I may have missed?
