They are probably different because they are based on flight tests, not calculations.

if I were to guess, and without knowing anything about this test, I think the lower red and blue curves are without g suit, the higher curves with g suit. if you notice, the convex points (most outward g value) for both the non-g suit curves (assuming that is correct assumption) is around 5.5. g curve. This value seems reasonable.

early ww2 planes, I do not believe were equipped with accelerometers to measure the g. Maybe the p47, iirc. So, this windup test, I don't think it is realistic to use that for your determination, if you wish to remain a faithful, non-quake pilot. If you start using g-meter, wonder woman view, or digging into the code, that might make you quake player by default.
