4 LPM is about 1 mpg surely? Which would be a lot worse than 'bad'.............

I'm working mine out at the moment (1.6 td syncro). All I do is reset the odometer and fill it to an inch from the top (theres a line). Then do the same after say 200 miles or so and enter the details here.

I get 38mpg in traffic, 46mpg at 50-55mph.

That sounds a bit optimistic to me. I think a lot of these figures are arrived at by dodgy methodology or inaccurate gauges and odometers.
Personally I just brim the tank til the pump clicks, then reset the odo (which appears accurate compared to gps). Then next time I fill up I brim it again and get a receipt, and write the odo figure on the back. This gives accurate numbers to work out the mpg with no guesswork or relying on the fuel gauge. I get approx. 30mpg out of the 1.6td generally, although I guess I could get a little more if I slowed down a bit...

I work mine out on gas, fill up to max do 180 miles refill work out MPG (around 4 to 4.2MPL)

The two trips I quoted were both well over 2,000miles each, brim filling and noting down the mpg from every fill then working out the overall average.
From memory....and it's been a couple of years, there were a couple of fills where the consumption hit just over 28mpg and several dipping just below 22mpg.
Predictably the 28 was on long flat motorways at 65mph and the sub 22's driving up and over the Alsace, Albiss pass and driving through Interlaken and up the windy mountainous roads to Grindelvald.
And then of course, the last tank and a half fully laden with 15 cases of beer and 60 bottles of wine.
Personally, I don't think that is bad at all and as accurate as you are going to get as it was based on many fills over a very long distance.
