"By the late 70s and early 80s, when Cohen started doing research at SRI,
the engineers were in the lead. But there was a problem: the improvements
seen in their models were starting to asymptote."

I can't find any dictionary coverage for "asymptote" as a verb (= 'to
approach an asymptote'). Examples on Google Books go back at least to 1896:

1896 _Journal of the Royal Statistical Society_ June 59/II:324 The curve is
symmetrical and tails off more or less rapidly in both directions, according
to the value of σ, asymptoting to the base.

1904 _Philosophical Magazine_ Nov. 47:589 The fact that the curves appear to
asymptote to this line shows that the overtones die away quicker than the
fundamental.
