I use a 5 string because I hate changing tunings. 440 all the way for me. However, one song I do has to be dropped to Eflat, or 1/2 step as I believe it's called. I was doing it by ear, just hold one fret down from the E on the A string, and tune the E string until it's the same. However, live, no one is giving me any time to do that, they seem to forget and just start the next song (I told them I really, really, didn't want to start having to tune things for one song, but I of course was told to shut up). So, I grab my tuner, and will set the hz to ?? 440 is normal, what is 1/2 step down? 439? 435? I feel silly asking but a quick google search and I still couldn't get the answer. So, I ask the masters at TB.
