Hmmm… sometimes the written word can be interpreted many different ways. My take away from the various messages here isn’t that there’s a “right or wrong way” but there are various techniques (especially in the world of a food plotter) that work just fine, depending on the goals of the person applying the chemical. If a person wants to be incredibly precise with their application, the sky and your budget is the limit on how fancy you want to get with equipment - fancier sprayer, fancier electronics, etc. If you just want “pretty dang good for a food plotter” results, there’s a bunch of good suggestions on here for that as well. Goals differ, budgets differ, opinions differ.
