Cleaning up the calibration mess is Y-Search looks tricky, given the length
of time it has been there.

One option might be for Y-Search to highlight all markers with ambiguous
calibrations in red, and then as people elect to confirm what ever
calibration Y-Search decides to use, the marker scores could return to
black. That way, the red would alert people to potentially unconverted
markers, yet not lose the data completely. Perhaps Y-Search when finding
matches could be trained to ignore mismatches on red markers?

Just the opposite. The "low" guys were there first, and established the
Ysearch standard, which (as Dennis cited) Dr. Krahn specifically endorsed.
For a while, Ysearch had explicit instructions to Advanced customers, to
convert high to low.

Mysteriously, those instructions disappeared at one point, and attempting to
persuade people to convert high to low became hopeless.

However, Dr. Krahn has never specifically countermanded his previous
statement, nor has anyone at FTDNA ever converted all the existing entries.
