They did, and I’ve yet to work out how the new relates to the old. I liked it better the way it was.
I just try to maximise all three required signal strengths, and then test extensively. If all things work as expected, repeatedly, then it’s good enough. What else can we do, since we now have no definitive values, or colours, on a scale that seems to have less granularity than before?
Not sure what they were thinking, other than it looks a bit ‘cooler’.
