Having served in 21 in the 80s I know the routes to the beige lid. A good mate went 21 -> 22, but had to serve a year in the Paras after passing 22 Selection. No-one that I knew of got to do 22 Selection from 21/23 with less than three years' TA service, so the timescales remain the same, and as you say, no-one in 21/23 would have picked up any medals at all, let alone that haul.
