fair scoring reasons some subtier ones Jury decided anyone beyond five top fliers after four rounds very close should permitted finals turned out Bruno Giezendanner beaten out 5th place spot flyofi

overcome under better conditions flight before judges 10 judges per flight rather five shorter time span reduce effects weather end controversy over questions should finals would settled flight line rather arguments pieces paper So Giezendanner flew finals able improve position some others did remained 6th Concerning averaging scores vs totaling several debates Jury followed precedent 1977 Championships Springfield Ohio decided totaling difference significant averaging best B flights could add up best finals flight especially considering complaints four rounds B flying Jury decided finals should count least much previous flights Thus although rule book gives some basis averaging scores Jury opted what felt fairest choice end made no difference although could have hassle Dave

rather arguments pieces paper So Giezendanner flew finals able improve position some others did remained 6th Concerning averaging scores vs totaling several debates Jury followed precedent 1977 Championships Springfield Ohio decided totaling difference significant averaging best B flights could add up best finals flight especially considering complaints four rounds B flying Jury decided finals should count least much previous flights Thus although rule book gives some basis averaging scores Jury opted what felt fairest choice end made no difference although could have hassle Dave

background story contestants aware first fact Bruno Giezendanner Switzerland added sixth flier flyoff although rules provided five second resulted scores being totaled flyoff whereas previous flights averaged both cases seemed strict reading sporting code FAI rule book would allow situations However FM Jury composed three dependent contest officials empowered take such actions rule book wording inadequate unsatisfactory meeting intent rules first case complaints during first three competition days some judging situations clouding results particular set judges scoring down middle 4s through 7srarely 8 9 also complaints previously agreed upon system having set judges maneuvers another B maneuvers utilizedwith some bad effects some fliers Also complaints higher normal winds day prevented fair scoring reasons some subtier ones Jury decided anyone beyond five top fliers after four rounds very close should permitted finals turned out Bruno Giezendanner beaten out 5th place spot flyofi point outofover400 Furthermore fourprevious scores counted instead best best B flights Bruno would have clearly 5th Therefore Jury ruled Bruno could fly finals inequalities previous flights could overcome under better conditions flight before judges 10 judges per flight rather five shorter time span reduce effects weather end controversy over questions should finals would settled flight line rather arguments pieces paper So Giezendanner flew finals able improve position some others did remained 6th Concerning averaging scores vs totaling several debates Jury followed precedent 1977 Championships Springfield Ohio decided totaling difference significant averaging best B flights could add up best finals flight especially considering complaints four rounds B flying Jury decided finals should count least much previous flights Thus although rule book gives some basis averaging scores Jury opted what felt fairest choice end made no difference although could have hassle Dave Brown placed second totaling first aver aging didnt happen either system Matt placed first Jury decision immaterial However has produced recom mendation FAI flyoff system better defined future need no
