understanding the nozzle chart to adjust pressure

[Dave B]

I warned you guys that I would ask dumb/rookie questions...

So I have a machine that is 4200 psi @ 4 gpm. Meaning I'm using a 4.0 nozzle size/ .052 orifice.

If I want to reduce my pressure to, say, 2500, according to the chart, I should be using a size 5.0 / .057 orifice. Is that right?

Want to make sure I'm reading the chart right and not over looking anything before I buy a new set.

As always, I appreciate the help.
