That's really interesting. I will see if I can get this to work within the limits of the student edition. I did try a similar approach earlier but it was not successful as it tended to be more suited to a lower F/D. However, this was with a circular patch at 6mm spacing and before I realised how to get CP so maybe. I will look again. I looked at that book myself and concluded the same and also that the small squint probably didn't matter too much.
It is more complex to make, but not excessively so and also maybe a retro-fit - someone (not me) needs to compare and contrast perhaps. If it turns out to be a worthwhile improvement, we can call it the "Patch Of Next Year" or PONY for short and sell it for £25. (only Brits of a certain age will get this joke)
If you can tell me the dimensions, it would help.
