How much km with half full tank ABT

Hello dear Audigemeinde. Would like to ask, how much km your daily kilometer counter stands, if the tank indicator is half full. At it is 250km. My Audi is en ABT, B4 Today I had the AI apart and all the Kontakes lubricated and sprayed. The water indicator is now again. I already have the adjustment wheel at the tank clock on stop. But the 250km seem with a little too little. One tank is enough for 700km, then only damp in the tank. (Of course never before pa ssiert 🙂 ) Greetings Patricki
