If I want a test strip I'll use a Kodak projection print scale on 5x7 paper.
More typically though I find exposure and contrast with my Beseler PM2L color analyzer and start at whatever print size I am after, mostly 11x14.
That analyzer, once I "got it" and once I get to know where any particular paper's B&W points are, can provide exposure and contrast settings that get me very close to the "right" base exposure on the first try.
At that point I want to see the whole thing to make sure there are no hidden issues I could not see with a loupe.
I minimize paper use with the analyzer.
