FWIW, this is the chart that I use.

In addition to the advice given , try and use natural light.

Also do not rely on one test. You need to be making the camera focus from infinity and min focus distance each time. Do 10 of each. Go with the majority result. PDAF is just not accurate enough to rely on one test
