Export threadEven if you used a compression gauge with a hose a mile long, the reading would be the same as one with a short hose like the one in the picture. It just would take longer to measure it. Think of it as inflating a tire: with the same supply pressure, the same tire pressure will be reached, but a big tire takes more time to fill.Proper valve adjustment on the tight side of in-tolerance would be advised. See what you get after with a compression gauge FOR SMALL ENGINES. Not some 454 chevy compression gauge with a foot long hose.

If you still see cross hatching and have 90 PSI compression with a compression release properly working, the rings are probably fine. However, if not and B&S does not sell them any longer, you may find some by a ring maker that are close enough to be file-fit to size. See, for example, https://hastingspistonrings.com/wp-content/uploads/2023/05/2022-AMERICAS-MASTER-CATALOG.pdf
If you have not done it recently, the valve work suggested previously could go a long way toward making the engine run better.

Throttle plate and choke plate fully open while cranking?Compression was done dry. Six or seven cranks with electric starter (until reading reached max).
