There's maybe a misconception here, as editor of the BJP weekly magazine and also the BJP Annual he published formulae contributed by other people and that includes Ilford & Kodak as well as the alternative colour developers (and others steps) from a German chemist Ernst G* (almost certainly working for one of the larger photo companies) as the formulae all worked well.
What most mean by the Crawley formulae are his own FX series of B&W developers first published in 6 articles in the then weekly BJP at the end of 1960 and January 1961, and only a few were revised. These were in the BJP Annuals into the 1990's.
As to the Perutz formulae, when Crawley started editing the BJP Almanac they were on the cusp of being taken over, still making their own films and the formulae stayed in the Annuals while the older films were still around. Then in 1964 Agfa or rather the newly merged Agfa Gevaert took Perutz over and their Perutz brand films used the regular Agfa processes.

I said 'his' formulas, didn't I? Those are the 'FX' formulas.
