I would be tempted to use a simpler and to compare subject. Maybe something like this focus pattern: https://static.bhphotovideo.com/explora/explora/sites/default/files/bandh-test-target.jpg

Print it out as large as possible, put it on a wall in a sheltered area (maybe your garage) and then shoot your tests in manual mode so everything else stays consistent. That way the only variable is IS.

For example, the difference between 1/250 and 1/125 of a second is 100%. If there was even a breath of breeze, it could make a difference.

Pick a particular spot in the printout, ideally near the center to avoid aberrations, and compare results.

BTW, here's the full article that image is from: https://www.bhphotovideo.com/explora/photography/tips-and-solutions/how-test-your-lens  It's an interesting read about testing lenses.
