thats why i back the psi off from 40 (my psi that i spray with out of the boom) to 30 when i use the lawnjet. I did a bucket check and its right at half gallon per minute at 30 psi with the lawnjet. so, i had practiced with water in a 1,000 sq. ft. area until i was able to put down .5 gallon per k like that.. so it would seem to check out for me, and i wasn't over applying at my pace. droplets are very close to whats comming out the boom. so i'm assuming i got the right idea here? everything is dormant now or has been pretty close, probably little risk to damaging anything at this point as I just spray bermuda now.
I'm not a fan of using the lawnjet so far, It is so hard to figure out if i'm overlapping to much.. i think thats a concern of mine more than anything. Its hard to see the edges of the pattern some time. I guess it takes getting used to. but i do not use this much. every now and then when i have to.

So...you have to sweep the same nozzle across the weeds at 4 mph. That is about 6 feet per second. Practice with water. Try to get the pattern of droplets to match your boom sprayer pattern on concrete.
