i think with EMC you also have to think what has been done feature wise that is not even in the main EMC release profiles that people have programed them selfs?

like one thing i did on a machine was slave my 4th axis to the spindle encoder feedback to cut gears with, took zero extra hardware only 10mins of my time writting some HAL code and away we went..
id not like to think what would cost me on my Fanuc machine todo that...

im sure there are much more that people have done and are possible that is not listed any where.. so counting features is abit odd way to go.. with Mach or EMC..
