Agree, but most people are mathematically challenged these days, especially those that grew up with calculators so they did not have to develop the mental skills to do complicated math in their head.
Even for the most math illiterate a gear calculator expressing the output in GI is about as simple and easy to operate and understand as possible.
For those who can't understand that 70 GI is 70 GI no matter how one gets there, that 60 GI is "less" and 80 GI is "more" with the data taped to the stem right in front of them there's really no hope.
Sorry Captain Fast, and BTW a 50T is
not a "big ring" either.......
