Hey Joan, thank you so much for taking the time to write the comment! I removed that misleading line.

There is a little bug in the way the test results are presented. In the “Scientific details” paragraph it shows the two “Most challenging correctly identified plates”, and the Δh for each. Then after that there is a line saying “Comparison: the two plates differ by…”. This line is wrong, it’s calculating the difference between the two Δh of the two most challenging plates. So for example if your two most challenging were both 2°, then that line will read “Comparison: the two plates differ by 0° in hue-difference” which is obviously wrong and has no meaning. It’s taking the difference of the differences.

Instead it should take the smallest of the two. Or just not write that comparison line.

This line could be very misleading because even someone with very poor discrimination could get a very low value here.
