there's so many variables that with draw rates on in-lines , Bill.
Things like PSI, heat and flow rates can make one man's in-line draw X amount, while another operator's in-line draws Y amount
When I was using in-lines, I mixed 50-50 water to chem for the high viscosity chems like
Ultrapac.
I'd do the same with JJ
Best to bucket your in-line with your TM set up to know for sure.
Simply measure a precise amount of juice/water mix for the jug.
Then spray into a bucket at temps and PSI you'd typically run while working.
after a measured gal has been sprayed in the bucket, then measure how much chem was drawn from the jug.
Now you can calculate what dilution ratio you used and adjust accordingly
