It has no connection with gear other than what gases are required.
Procedure of performing it has connection with gear e.g. we use wet notes when agreeing upon average depth and bottom time which define decompression. IMO it's hard to separate tool itself from applying procedure because the efficiency (performance) is the most important part of the story. Without it, it's just a theory.

There is no magic behind Ratio Deco.
I agree with that - it's just result of analyzing specific part of whole decompression picture.
