My ARRL books go back a decade or more
and the graph showing gain per boom length
has several curves based on different measurements
e.t.c. Has a graph been made based solely on NEC
program findings over say a perfect ground and at a uniform height?

They probably have been done but there will not be much difference between
them and the ARRL graphs. Its been long known how to calculate antenna gain,
computers just take the teadous labor out of it.
