Since I upgraded my tractor this winter, I plan on recalibration and this is the method I plan to use. Adjust the nozzles and the tractor speed until I feel I get adequate coverage of the trees. I will then fill my tank with 50 gallons of water, and spray it over a prescribed route. When the tank is empty, I calculate the acres sprayed. From that I can determine the number of gallons per acre. To that number of gallons, I will add the chemical required per acre. Since we are high density, well pruned, I multiply by .7 (captan: 6# x .7= 4.2 #). If I travel the same route, I will get the required spray per acre.
A different question: my new tractor has an enclosed cab (no more monkey suit), with an activated charcoal filter. What is the opinion on the necessity of also wearing a respirator. EPA would say yes, but are they too cautious.
