Regolith floor material

[FRC2028]

Elsewhere GDC says the Lowes and HomeDepot material may be used and quotes from "Bills Blog" the coefficient of froction as :

"What’s important is duplicating the coefficient of friction; 0.05 static and 0.04 dynamic."

But the Section 10/KOP says:
10.2.4.1 Wheels
The wheels supplied in the 2009 KOP are very different from previous years’ kit wheels. The tread material is Celcon M90, and has the following coefficients of friction on white, rippled fiberglass plastic sheet
Inline, static: 0.06 Inline, dynamic: 0.05 Transverse, static: 0.14 Transverse, dynamic: 0.10

So is the Lowes or Home Depot materail REALLY the same material? And is it the pebble finish?

[GDC]

Yes, it really is the same material. Honest. Cross our heart and hope to die. It is the same stuff.
