It's not really "complicated" as much as it is tedious and much slower than it used to be. Kinda like most of the new systems. Thankfully, I have settings to turn most of this new crap off.
But the signal detection isn't that complicated. Just make a triangle with the three nodes around the signals. Gotta make sure the inner circle is big enough to detect the signal. Going big is an option, but going too small isn't.
