I found the following reference guide addendum about the daylight measurement path:
In the requirement it says: "Measurements must be taken on a 10 foot grid.." and in the calculations section it says : "Record indoor light measurements of all regularly occupied spaces on a grid that hast at least 4 points in a room and with a maximun grid interval of 5 feet."
So I dont understand how the grid should be.
Another question, do measurements need to be done at an specific hour?

Measurements can be done at any day, any time.
I don't know about the 10 ft vs. 5 ft spacing, but I would use the NC guide that says spaces that are 150 sf or larger use a 10 ft spacing and spaces that are smaller, must have at least 4 points.
