The first number is flight time the second number is tach time.
C172M: 
C172L: 
I guess an “average fuel burn” is better measured in TACH time?

Which times are used for the fuel consumption calculation? If block times (or airborne plus some X mins) then the consumption figure will be pulled down by ground/warm-up/taxi time being included in the calcs?
Airborne time. We never use tacho time (except as a check that the airborne time is reasonable) or block time.

Flight time consumption is lower than tach time consumption? So they are using more fuel on ground than in the air ?!?
Flight time is airborne, and most people run at lower power settings.

it matches my own observations.. flight time is usually ca 10% bigger than tach ,that means the consumption should be lower..
Those Annemasse Robin DR400 prices are a good 40+Euros an hour more than at my Aeroclub nr Bordeaux.

Of course. Because they are so close to Switzerland. I assume at least half of their members is Swiss. And they love these prices.
The airport is 30min walk, 10min cycle and 5min car drive from Annemasse and 25min car drive from Geneva, I doubt it’s comparable to many airports in Europe, maybe LeTouquet, SanSebastian and Cannes? or listed by A_A in Sweden?

I’m not certain what you are getting at here. Anyway, the population of Uppsala, where my club is located (10 min by car from the city centre), is the same as that of Annemasse and Geneva together.
