RE: plan enlargement
For example the Goldberg Tiger 40 = 61" and the Tiger 60 is 70" then divide 70 by 61 and you get 1.15 or 115%
Super Sportster 40 = 55" and the Super Sportster 60 = 61" then divide 61 by 55 and you get 1.11 or 111%
Four Star 40 = 59.75" and the Four Star 60 = 71" then divide 71 by 59.75 and you get 1.19 or 119%
