The gauge is, at best, merely an indicator, accurate mainly with itself. i.e. when you find the perfect shot, the gauge might be almost anywhere on the scale - and the next good shot will be around the same. Mine does best with pressure a little above the top of the colour segments.
Sounds like you're getting in the range. You could try 1 step finer and tamp a lot lighter than the 15kg or so and see how that goes. I have had blissful coffees pour in 45secs and even 1 or 2 that took maybe 60secs with no sign of blonding and tasted great. Again the time of 60ml in 25secs is just an indicator - depends on the bean, the grind, the machine and your tamping.
Something to remember - most grinders adjust best when either empty of beans or when running. It confused the hell out of me for a while as I would make an adjustment and either see no change or even have it go the wrong way. One good thing about an EM0480 grinder is the switch at the side - you can flick it up and the grinder runs while you use both hands to adjust. It's a bit awkward with the EM0450/440 to try to press the button and still adjust things. (not sure which grinder you have)
I usually just empty it, clean any stuck beans from the grind surfaces and make the adjustment - experience usually means I get it right within one or at most two adjustments, but it's a bit of a piss off to empty, adjust, fill, grind, empty, adjust etc. Makes for fast learning.
I've also found the SB baskets seem to work better with the tamped coffee at least 4mm down. With both the 6910 version and the 7000 version, that sits the ground weight at about 15g - 16g. (my scales only do gram accuracy)

A word of warning - one of the worst things to microwave is milk. MW works by breaking apart molecules to release heat and some milk byproducts are toxic. Also, the reason why there's a 'best' temp for frothing milk is to avoid getting the milk to where it begins to break down. The steamer on the 7000 is pretty good, so it isn't really much of a chore to use.
