OK.

Now the FED also puts out their own computer program for Athletic Rules Study. They also have on-line stuff available for both "Officiating Procedures" and "Officiating Basketball Methods".

They also have mechanics and other training videos available iirc.
How is the IAABO stuff better, more-complete, etc. than what the FED is putting out? What are the differences and why are those differences better?
