   Dear fellow forum readers,
   
   I would like to ask what methods are being used to calculate (or make allowances) for the extra areas that you spray or apply a granular product to when making an application? For example, it is easy to calibrate the theoretical output of your boom sprayer or the application rate of a granular spreader, right, but how do you calculate to allow for all of the overlaps (boom spraying), and the extra product applied outside of the designated areas you want to apply the product to (both boom spraying and granular applications)?
   
   I ask this question as I am trying to calculate/impute realistic data (or as close to) for my TRIM's software so that the more accurate total product rates can be calculated relative to the actual area product is applied to and not the exact areas of the golf course area as measured by GPS or survey?
   
   Thanks in advance,

   I figure about 5% wastage for those larger applications when I order product. Typically this is dead on. Significantly less on small applications like greens and tees. Probably closer to less than 2% overlap and wastage.

   Well if you know your acreage say 3 acres of tees and you spray at 100 gallons per acre, you would need 300 gallons to treat the tees. Whatever you use beyond that is your "overage"

   I typically figure for about 5% as well. Which does make me wonder where Smithco comes up with their "20% overspray" figure when trying to sell their GPS guided systems...

   I use Planimeter and map the course by area and it is very close, works great and is fast.
