> BTW, the Record is comfortable with the 13 th top, but I could never get
the preceding Gran Sport to work with anything smaller than 14: just plain
skipped, no matter what chain or spring tension I used. But, in its
defense, it was marked "14 a 26" denti (or something like that).

That's odd. Did the Gran Sport not pivot as far forward as the NR? If so, it wouldn't wrap as much chain, all other factors equal, and without enough chain wrap, the chain's going to skip.
