I ran a group of tests and the results we have so far, is if there is no primary name match at a fork in the road, the next check is for a alternate name match, followed by a segment type match if the alt names don't match.

The test results ↓:

I got results on testing alternate name effect on best continuation. √=instruction, X=Best Continuation, Green=No match, Orange=Primary match, yellow=alt match, purple= the alt of one segment match primary of the other segment.
If primary names match it's BC, if alt names match it's BC (NEW), if a primary matches one segment and an alt matches another - the primary match is BC, if a primary cross matches an alt it is not BC. So the BC algorithm should be modified to show order of preference; Primary name match, Alt name match, type match.


I propose to add this step (do alt names match?) Into the best continuation algorithm.

Any comments?

2) primary name
3) alt name*
4) type
*alts are only considered if s-in has an alt name.

It has yet to be determined the priory of a primary <> alt cross match, though its likely higher than type, and lower than primary. This is being tested now.

I'm also testing; if there's a preference when cross matching of the primary name being matched is on s-in or s-out. If s-out must have an alt name for a cross match to occur.

It does already right above the table of contents, if I'm understanding you correctly.

A simplified easy to understand interactive version of this page is available here.
