The table put out by Bob Marcellus gives essentially the same results. The "1.9" method is correct only for a fruit of about 585 pounds.The weight/OTT inches ratio progressively changes over the whole range. Anyone can check this out easily using the OTT tables. Hope this clarifies the matter for those getting conflicting results.---Al Eaton >>>> I guess my confusion is coming from the Stellpflug table in Langevin's book on page 109. It seems that this table is based on circumference only measurements. I assume that this is in error or there has since been a refinement of the table using all three measurements. Please Al just a little more patience in helping me out. Ciao, John
