Good post there 'rutan':-) 4000 hrs in a C210...you poor bugger!
Much has been written about turbulence & is a very subjective subject.
What one pilot would do to reduce it's effects on airframes & pax could be somewhat different to the next pilots reactions or lack thereof.
Often yr cruising in light turb at a typical cruise speed then hit almost severe trub in an instance & that being the case the recommended turb penetration speed for such a situation is instantly exceeded so like most things in aviation ones personal comfort factor is yr guide here.The book No's are really only a guide in some ways.
