One major drawback in cumulative scoring is that it is more complicated task in keeping track than in the transfer system. In the 1980s at least two national level scoring scandals (one in 1985) in which the national professional number one was decided after the Grand nationals underlined this. There was also a scoring mix up during the 1983 NBL Grand National in which it was thought Brian Patterson was the winner for two weeks but after a recount initiated after Eric Rupe protested gave Eric Rupe the number one for 1983. An even larger scoring scandal occurred in 1985 in which pro racer Peter Loncarevich apparently beat Greg Hill for the number one pro racer by a mere 3 points. Greg Hill's wife Nancy (who was the bookkeeper for Greg Hill's BMX bicycle company Greg Hill Products) kept an independent accounting of the season points of Mr. Hill's closest competitors and detected an error. At his wife's urging Mr. Hill ask for and received an audit of the points and the NBL confirmed the error had taken place and awarded Mr. Hill the pro title for 1985.
