Thanks to everyone again..i think now to be almost able to fully understand how to transform Command Decision scenarios into games playable with RF.
As concern the new RF ratio of 1/45.1/15 that you mentioned, of which i m aware, i suppose that' is principally useful for campaign based games and to plan our miniatures armies following the so called "battle groups" army lists that have been published so far..it looks like the abstraction systhem called "bathtube" which is still good, despite the scaling, as it still allows to stick to the original 8 figures infantry companies/platoons and 2 or 3 model tanks companies/squadrons..in short, "basic units".
It's probably worth stating RF and CD are very different beasts; I was a CD player (more Combined Arms TBH). CD was very much structured around real organisations and represented scaled down weapons systems, such as AT or infantry guns.
RF basically started with an infantry section representing a platoon - with the consequent distortion - 15 panzerfausts firing at 5 tanks as if it was 1:1. CD would just give a platoon stand an AT rating.
CD used "bathtubbing" to scale up so the platoon stand became a company or battalion etc. It kept all the various weapon stands etc however.
The new RF approach by contrast, scales up the stands, so a platoon of tanks = a btn, but eliminates a lot of the weapons, just keeping the main battalions.
