EDITED FOR CONTINUITY
The original (deleted) test shows the beginning of a valid flare test.
The first points to the right of the origin show a possible "flare factor". The displacement on the x-axis... it's how much light (if you can deduce the mcs) the flare added. Taper would start there and within a few steps to the right it would re-join the Non-Flare curve.
A good test to determine flare could be to shoot a variety of gray patches that meter says differ by one-stop each, surrounded by a white background.
