-why not just say 20,000 pound crush strength for gravelless pipe, instead of H-10 or H-20 (AASHTO) (12VACS5-610-930, F.2.f)
-Why is gravelless area less than gravel area in df size, what justifies it? (Table 5.4 and text –950, D.2)
-Drip dispersal B.3 requires 6 inches, manufacturers like to recommend install at 4 inches, justification either way? (–955, B.3)
