Sorry if this seems overly picky but you're asking the wriong question. There are no measurements for a "properly set up Horizon", it all depends on the tonearm you've selected. For a Rega you have several choices. If you use the one point protractor supplied with the arm which yields Stevenson alignment then you end up with an overhang less than 17.24mm. The problem with Stevenson alignment is that it is generally considered to sound worse than Baerwald alignment due to a different distribution of distortion across the record surface.

If you mount the arm at Rega's specified 222mm then the arm's effective length is 240mm and the overhang should be 17.24 mm for Baerwald alignment. The problem with 240mm effective length is that some cartridges will end up at the extreme end of the headshell slots. But many don't. If you run into that problem then changing the effective length to 237mm by changing the mounting distance to 219.5 or 219mm will put the cartridge closer to the middle of the headshell slots. It's very difficult to measure overhang with most alignment tools (my preferred Wallytractor is the exception) so it's not really a useful number.

If you search the VA archives for postings with "Rega" and "alignment" written by "Garth" you'll find a lot of good information on this subject.

Where are you located? Perhaps there's an Asylum correspondent in the area who would be willing to come over and give you a hand.
