Yes, the guide actually says
The tint control is a legacy control that exists from the days of 480i composite video (not to be confused with component). Tint is used to adjust for hue errors in the three secondary colours. Since it affects all three secondary colours at the same time, it is pretty much useless for precise calibration purposes.
2. Instructions for setting primaries are pretty straight forward, but for secondaries, the guide lists reference values for REC709 (and REC601) and mentions to adjust Hue and Saturation of each color control.
If you have CMS controls for Primary and Secondary colours, you can adjust all colours the same way, first the primary then the secondary. They do interact somewhat, so repeat the sequence to check.
3. The x and y values are affected by both Hue and Saturation?
Yes. It's much easier to view the CIE diagram when you're adjusting them, rather than viewing the numerical values of x & y.
Also while changing Hue and Saturation, the Y value is also getting affected.
Yes, you do have to iterate between them.
I have created a simple excel sheet with all required steps. It will ask you to enter the Y value at few steps and calculate the corresponding %ge Y values for next steps.
I'm not sure why you're calculating the values "off-line". HCFR pre-calculates all the target values based on the measured white luminance; all you need to do is to match the measured values to the calculated values as closely as you can, which will also minimize the delta-E. As mentioned previously, the CIE diagram gives you a good graphic view of the xy vaues, while the "grid" gives you the Y value.
