It is 592mm for the archetype if your measuring spoke head is flush or just below the nipple driver flat of the nipple you have loctited in place. It is 595mm if the spoke head is flush with the top of the nipples.
If you use 595mm you must round down by at least 1mm or you will run out of threads. I use 593mm and never run out of threads or have thread exposed i.e the right spoke length.
If you are doing 32H 3x rear with hubs with 44-46mm PCD then spoke length is 288mm/290mm.
