@AllamFarmer@windypopfarm @KristjanHebert Not a lot, most of the cost is from storage space and users. We link Google Sheets in for a lot of functions. Countdown and approvals are handy add ons.
The green graph assumes a farm owned sprayer application cost of $3.62/acre (Sask Farm Machinery guide), the blue graph is a custom ground application cost of $6.50/acre. Trampling losses assumed @ 3%. Bumps are due to rounding to the nearest whole number.
