It looks more like 4-6", 2-3" and 1"... I think they have varied it slightly year to year, If you read through some of the discussions on the 04,05 and 07 robots from 233, I think it says what sizes they use. It's the exact same principle, except the sliders are inside of each other rather than next to each other.
