That
chart has some real values, such as the ability to fly business class between the US and Europe for 90,000 miles roundtrip instead of the usual 100,000, the ability to
pop around Europe with several extra flights thrown in for 115,000 miles in business class instead of 100,000 miles roundtrip plus another 20,000 miles for each and every additional intra-European flight, and the ability to fly to Australia in business class
via Asia (not normally allowed on a single award ticket) for an extra 25,000 miles — and make stopovers in Asia, and throw in Australian domestic flights at the same time.
