New machines, new injectors. Whats the cut?

Hey guys my new machines arrive tomorrow and im extremely excited! Since we are upgrading from 5.5pm to 8gpm i was wondering exactly what the recommended cut would be with new injectors and more gpm from the machines. We are using a 65 gallon chem tank on the truck. They include “20% HIGH DRAW CHEMICAL INJECTOR” which i assume is 20:1. Im not great with understanding mixture percentages as you guys explain them. Is there a chart to figure out percentages?

Math formula

1 divided by 20 = .05

12.5 SH (or whatever strength your using ) * .05

= .625 SH hitting the siding

I try and stay close to .8. But depending on your weather and other factors that may be strong enough.

As far as the 20% goes… I’m not quite sure how they come up with that.

In actual math that would mean 5:1. But I know that’s not what they mean.

We have always gone fairly hot with mix. Maybe a 2SH / 3 H2O mix with a 10:1 and havent had any issues and works pretty well. But i feel like im over using. However, with only running 1 chem tank for HW mix and RW mix i feel like hotter isnt necessarily bad this way i can just throw in the drop stick and pull the same tank for both chems

with that being said, on a smaller tank id like to go 25/35 in a 65 tank. Which should be plenty for both mixes
