This is a follow-up on this question (How to make bottom for a big drawer)?
I have also read this one (What are the minimum, maximum, and optimal depths for dadoes, grooves, and rabbets) and I'm not entirely convinced it can be applid to particle boards "as is".
I'm making a large drawer - 130 x 60 x 18cm (on the inside) with 3-4 muntins (cross beams) in the middle. Sides and muntins are planned to be made out of 16mm particle board, bottom - out of 4-5 disconnected (by beams) sheets of 6mm plywood.

I have got two questions:
What is the rule of thumb for depth of grooves in particle board of given thickness? Should it be still 1/2 of the thickness (8mm) or less, given particle-y nature of the material?
How far should I offset from the bottom edge? I reckon 1/2 of the thickness (8mm) should be minimum as well, does it need to be even more than that?
Sidenote: I'll be using a router table with 6mm bit to cut the dados / grooves, if that is any relevance.
