Yeah, but I was only considering two "general varieties" with their transcriptions, the ones you find in dictionaries. If you start to consider all the varieties, you'll never stop. I just noticed a mistake...
Anonymous“NOW ----- In BrE it's more like /ɑʊ/, in AmE it's more like /æʊ/”

There sure are accents where it's different. But it's not surprising... in the UK there are so many weird accents that some people don't even seem to be speaking English, lol.
