I've got a paper safe with shelves that I swear I put test strips of grade #2 on shelf 2, #3 on shelf 3.
When I "run out" of test strips, I take the big scissors and go to town on a sheet of 11x14.
I cut about 2-inch strips from the 11-inch side. Last night when I did that, I had a strip that was a little less than 4x11 inches remaining. I decided not to cut it in half.
Only problem I have to deal with at the moment - I swear I picked Grade #2 strips last night but they proved to be #3. And I cut a #2 sheet of paper last night and added it to the sheets on shelf 2.
I have no idea which is which any more so I might have to throw out the strips and cut a new sheet.
I hate this prospect and am thinking of marking in pencil on the top and bottom backs of each sheet... "A - A" "B - B" etc. and then snipping an inch and popping a sensitometer test on a tiny piece of each sheet.
Going forward, I think I will pencil the grade on the back when I cut strips to prevent future mix-up.
Problem last night proved test strip was #2 and print was on MGIV, I grabbed the wrong box. My greenish Aristo must be giving me Grade 0 unfiltered. Tonight on Galerie 2, the print from last night matched the test strip very nicely.

Haven't made a test strip for years, not since I started using the Analyser/pro from RH, it is so good I find I no longer need test strips

I only use test strips, regularly, for prints over 20x24 inches. Since I now use the Heiland Splitgrade system, my initial exposure gets me in the ballpark, and dodging/burning is easier to determine (for me, anyway) in the context of the entire print.
no, i'll continue to make test strips on 5x7 paper:
test strips are invaluable to me. no electronic tool can beat them in my opinion.
+1 I like full sheets as well- Murals I cut a large piece of paper off the roll and do a single exposure.

I believe the OP was posing the question regarding the cutting of enlarging paper (test strips) to determine either general print exposure or specific areas in need of dodging or burning, in order to avoid the "wastage" of an entire sheet of paper (not my preference).
A test print, whether by printing device or the simple overlay of a burn card, is made by over exposing a single sheet of paper, of the desired enlarged size, to progressively greater, uniform, amounts of light in order to determine base exposure for the entire print, as well as areas in need of either additional light (burning) or withholding of light (dodging).
It will all get you to the same place, sooner or later, easier than not, more or less expensively, depending on preference.

Your illustration is a classic, and I like the way you further refine it on your site. You provide a lead that is worth following.
It doesn't provide as much information, but I try to accomplish the same goal using a 2x11 strip of paper laid diagonally over the important subject. With the strip behind my back, I turn the focus switch so I can see where I have to put the strip. Then I turn off the enlarger and drop the strip where it needs to be.
I make four or five slivers by moving a piece of cardboard about a half-inch in "third-f/stop" increments. I'm most satisfied when I see it go from "too dark" to "too light".
