personally i think that scales are overrated as a diagnostic measure - I use them once or twice when setting up a new machine and then never or very seldom look back yes in the hands of a capable barista or under expert guidance they can be a useful and informative diagnostic tool - no, unless you have someone to guide you in this process initially you risk over complicating what should IMHO be a straightforward and hedonistic experience if it works for you then by all means do it, but weights and measures are not the be all to end all in my opinion if anything id be more inclined to keep experimenting until you get a result that you're happy with, and then by all means log that, and use it as a variable to revolve around are individual palates different and susceptible to different influences? yes absolutely, but only you know what flavours / profile you like, and volume in / volume out may or may not help you find it anyway, id take everything with a grain of salt and go what works for you!
