There was substanial analysis to determine the subset and
most frequently used. The emulated instructions even had
optimizations even though they fell into the infrequently used
bin.

I always
wondered what the VUP rating would have
been were they not emulated.
Hopefully about the same, othewise they did
a poor job of selecting instructions to subset!
The instructions that they did not implement
were those that were infrequently used and
cost too much chip real-estate.
