the fan test does not support the theory of groups with large phase offset for either A7R5 or A7R6. However it doesn't provide ANY insight about the detailed row / col timing diagram of the sensor. There could still be phase groups with very small offset. I no longer have the vintage A9 to see how it would have looked like.
I really don't want to speculate on this, there are correct ways of measuring the exact sensor timings down to sub micro-seconds but it requires using some specialized assets... I can't use my current setup to measure beyond readout time , maybe some day I will....
you can also see the difference between the readout times between the two cameras

I don't think one can measure the line time or the phase offset using the standard LED setup as the rise time of LED PWM drive is unknown and can interfere with the measurement.
