I was attempting to lay out the pattern for the BR111 Triangulo engineered flooring I purchased. The lengths are 36 (4), 30 (3), 24 (2), 18 (1). I'm at loss. The BR111 instructions make it look like the first row is 4,4,4,4 second row is 1,4,4,4 third row is 2,4,4,4 and the fourth row is 3,4,4,4. This obviously want work and I can use some help here. Is there a recommended pattern based on these lengths?

Here the link to the instructions.

Second question. I layed a few of the boards on my slab and accidentally left them there overnight. Based on a calcium chloride test my slab has a moisture content that is less than 4%. Should I cull these boards or will they be okay?

With a calcium chloride dome test, the concrete needs to test below 3 pounds per 1000 sq.ft. That doesn't mean 3 pounds is OK, but it better be below 3 pounds.
