The 'conversion" also changed rules at least a couple of times - from 2.01.71ht rounds up to 2.01.8.8, or .2.01.75 rounds up to 2.01.8 but 2.01.74 rounds down to 2.01.7. It was an era when both Ht and FAT were acceptable for record purposes. That is no longer the case.
Also, I believe the conversion from Ht to FAT was .14 for events over 400m, but .24 for the sprints.
Thankfully this arbitrariness is no longer relevant.
A bit surprised that it wasn't mentioned that Decker was much younger than Watson -- doesn't this invalidate the performance since they weren't the same age to the exact month (typical LRC obsession with age)- so Decker's was the superior performance, not even including the difference in the track quality.
Did Decker win the race in which she set the record? That, too, would add to the performance.
