 Contrary to popular myth, this was not the primary reason for the change in javelin design rules that came into force starting in 1986; the relevant change of moving the javelin's centre of gravity forward by four centimetres had already been officially proposed prior to Hohn's record throw, not only to shorten distances but also to get rid of the then frequent flat or ambiguous landings, which often made it hard to assess if a throw should be declared legal.However, Hohn's record-breaking throw accelerated the process as throws of his distance were in danger of going beyond the available space in normal stadiums.Hohn has been a professional coach since 1999.
