With the improvements in the MGS, how much down tolerance do we have?  Will it pass at 27" or lower?

I understand that in light of the G41S tests that got raised to 27 ¾" by virtue of metric rounding for English units.  So how far down do you think the MGS could really go since it is a much better system then the G41S.  Is it worth doing some modeling or testing.  The reason I ask is in regards to maintenance activities, leave in place on future 3R projects, etc.

We have been recommending a downside tolerance of 27¾ in.

My opinion is as follows:

MASH " maybe 27" to 27½"

NCHRP 350 " maybe 27½" to 27¾"
