July 23th, 2013 (F1plus/R. Baillie).- Earlier this week it was announced that the Austrian Grand Prix may be returning to the calendar, with a provisional slot penciled in for next July.
Along with the inaugural Russian Grand Prix, scheduled to take place next November, the calendar will contain 22 races, raising questions about which races will have to go to make room.
The sports commercial rights holder chief, Bernie Ecclestone, said: "We will have 20 races, not more".
Despite more circuits joining the schedule, it seems to naturally regulate itself with existing circuits dropping off from the calendar, as they are unable to pay the hosting fees.
There's an unwritten rule that there should be no more than 20 races a year to avoid putting strains on the team.
Just adding a couple more races means that the sport will be eating into the summer or winter break or more back-to-back races.
Not only does a busier calendar put strain on the team personnel, who spend a huge chunk of the year away from their families and friends, it puts pressure on team’s budgets.
Like every other business, finances are important and with the current state of the economy the teams need to be careful with every single penny they've got.
More races means teams have to cover more costs for flying staff out, accommodation, paying for their time even down to providing their hospitality suites with food.
A couple more races could mean that teams budgets are over stretched, something that could also lead to limitations with car development hindering in-season progress as a result.
