Busbar sizing: FORMULA, THUMB RULE, TABLE ?

I’ve seen a number of “thumb rules” examples on CR4 forum :
“0.6 amps per sq mm in case of Aluminium and 1.25 amps per sq.mm for Copper”
” for Aluminum 0.8 amps for sq.mm, for copper is 1.25 Amps per sq.mm”
“0.6Amp/mm2 is fine for Alu, 1 Amp/mm2 is fine for OFHC Copper”

There are also some general dimensioning tables like the ones given by Copper Development Association.

Do you use such formulas or tables ? Which ones ? When and how do you use them ?
