Personal View On Speaker Cable Lenghts?

There’s a current thread discussing this in all detail:

Naca5

So the recommend length of naim naca5 is 3.5 MTRS per speaker , my speakers are 2.2 MTRS apart so I’ll have approx 2mtrs coiled up doing nothing , surely this can’t be right ? I know that it has to do with the resistance measured per metre but does this still apply to newer equipment . I’m using SN2
