FIAC started holding its own BMX World Championships in 1984. At the time the IBMXF and FIAC were two separate International sanctioning bodies that both held BMX World Championships. However, the IBMXF's was far more prestigious, professionally competently run and established than FIAC. This was because FIAC refused help from either the IBMXF and the American for profit American Bicycle Association (then as now only one non-profit BMX sanctioning body per nation is recognized by the UCI as representing BMX in a nation. In the United States's case it was and is the NBL), both far more experienced at the time in running BMX races. In some nations if you race in the IBMXF circuit (see above) you could not race in the FIAC circuit and vice versa, akin to not being allowed to race NBL if you race the ABA circuit if they had such rules in America. FIAC had odd (to Americans) conventions and rules in conducting races, most likely grafted on from road racing in which was FIAC's only experience. For instance not only did you race three times to determine average positions in the motos to advance the best four riders to the next stage in racing, something Americans were familiar if they raced NBL, you also, if the class was big enough, raced the eighths, quarters and semis also three times and the best racers qualified for the Main. Then if you did qualify for the Main, you had to race the Main five times to find the final ranking of racers. In the US only the Professionals in the 20" class raced the Main multiple times and only three times at that in either the ABA or NBL. If anything this put a premium on consistency and lowered the luck factor to a bare minimum. However, it was very time-consuming, even at races scheduled over two days.
