I've read the PRS description for the 2020 594SC twice now, but they don't seem to define what the "+" means? Wouldn't a 58/15LT+ just be a 58/15? or perhaps a 58/15 "-"? I'm really just being a smartazz, but throwing some of these terms out without a real explanation seems like hype. Perhaps I missed a post or Youtube vid that explains it? I understand LT=low turns=slightly lower output and greater clarity, is the "+" some of the turns added back? So confused......... But I love the new models!
