It seems that if you want to set records, you wouldn't use a
Selectric, but rather an old IBM Electric:
"What?s the fastest typing speed ever recorded? The top speed ever
achieved by a typist, 216 words per minute stands as the record, set
by one Stella Pajunas in 1946 on an IBM electric. To give you an idea
of her accomplishment, sixty words per minute is considered good
professional speed. The record for top speed for over an hour of
nonstop typing is 149 words per minute, also set on an IBM machine."
..and I believe that the endurance record for typing is 276 hours,
but I don't know what the rules were.
