Which was exactly my point in those other posts last week, 3/16 attachments give you no margin of safety, 1/4's are a much better choice, 5/16 would be on the border of overkill, but you wouldn't have to worry about your lap belt bolts pulling through the spar and failing your rear spar if you encountered turbulence. You also wouldn't have to worry about being knocked out if the attachment failed... Just some food for thought!
