Ram Connection single plate thickness check

Question

The maximum shear plate thickness is checked via AISC 360-10 chapter 10 under the "Extended Configuration" checks (page 10-104) to ensure that the moment strength of the plate does not exceed that of the bolt group (to help ensure ductility). 
 There are a couple exceptions to this, but I don't think the program is considering them. Can you confirm this? 
 - For a single vertical row the plate thickness is less than d.b/2 + 1/16" and L.eh>= 2*d.b 
 - For a double vertical row.... (same as above) 
 Also if the eccentricity "a" (from weld to center line of bolts) is less than 3.5" then the connection really isn't an "extended" plate. so this would be another exception (however the check is same)/

The program help indicates that those provisions still apply in the extended case, but the in the output for a connection with 2 columns of bolts, I see the max thickness increase based on gage and bolt diameter well beyond the d.b/2 + 1/16" limit, which confirms what you are saying.

Thanks for the files, this clear up a lot. 
 In this case the connection is not extended or even non-standard. Thus the plate thickness limit is taken directly from Table 10-9. When n <= 5, the limit is d.b/2 + 1/16" as you noted, but when N>=6, the limit is reduced to d.b/2 - 1/16" (in standard holes).
