I Have notice in the past in some races from the 50-60-70s of Formula 1 and they had races with 80-90 or more than 100 laps, for example the Watkins Glen race in the USA where Jim Clark won, it was a 110 lap race, I saw that it can be taken on cars. more than 190 liters of fuel in the game.., or we can races at 110-130 or 150%
you can ask to Jack Basford or José Trujilo if it is possible there will be an update like this in the future?
Some F1 races in those times were semi endurance races that lasted 4 hours or more. Or the track lengths were shorter than the average and still lasted 3 hours or more. Most people, even when taking for the scaling of 2x speed races, would not have the time for that sort of race time duration. Not saying that it would not be interesting in how boring and how much of a procession such races would be in Igp Manager.
Also, may I please advise you that this is not just an F1 management game. It is an overreaching formulas management game.
What may be interesting, though, as a one off for those whom want to do an endurance race, is maybe to set Le Mans up in here and allow a 6-8 hour duration race on 24 heures de Le Mans day.
Do that for 20 servers over 4 race times with a 64 team entry and you can have 80 winners at Le Mans each year...
