just an Excellent tool and a very useful fuel calculator. The only thing that keeps irritating me is, that it chooses the 2021 tracks for my 2019 GT4 championship, so i'm always changing the years. Not that dramatic, but I noticed, that if you change the year for instance the Misano track in the fuel calc. down to 2019 you need about 10l less fuel. That's why it irritates me a bit I don't want to end up without fuel after 1 hour of race, is there really that difference between those years ?
