There is no longer a limit to  modulation percentage.  The FCC deleted the
former rule that prohibited amplitude modulation in excess of 100%, back in
the late70s.  They probably thought the rule was extraneous, believing or
hoping that amateur AM would soon  die out, or that the FCC would  outlaw
it. 

That was the same proceeding in which they also deleted the former rule
against simultaneous amplitude and frequency modulation, making Timtron's
"SBE" perfectly legal.
