Something like a 2x4 mounted to two of these leveling feet might also be useful. Something that could just grab onto the 2x4 without requiring screws would be more versatile, and something with a broader foot base that handle an uneven surface might also be good.

I built our paver patio (750+ sq ft) over 20 years ago. On graph paper i plotted a slope away from the house and a crown off to the sides. Marked elevation changes probably every 2 feet. Calculated the height difference from the level line at the house and drove stakes with the paver base height marked guided with use of a transit

This sounds complicated but wasn’t. You can easily screed between stakes 2 feet apart. Still live here and patio has held up.

Good luck.
