I have noticed the fuelling estimates vary accordingly. ie, at overnight-cold start-up the range may be optimistic due to the overall average MPG counter, but as it's initially running rich both MPG and ranges do get quickly downgraded and once the engine's warmed up and some miles into the journey it will begin increasing the figures again.

I do think it's therefore more accurate than you're giving it credit for but of course, it's not infallable and if you don't follow the instructions, may lead to malfunctions. I've caused the display to glitch or even stall after using Diagbox for instance. But a counter reset will clear it.
One thing I won't do is brim it past the second click. The first click is overzealous due to foaming/splashback but my reckoning is if you fill it too much, you risk losing it out the breather.
