Lotus team principal Eric Boullier has joined the growing chorus of people to dismiss suggestions the current Formula One campaign is a lottery.
Lewis Hamilton extended a new benchmark in the sport with his win five days ago in Canada, becoming the seventh different driver to take the chequered flag in the opening seven races.
It has led to some criticism the season is too unpredictable, but not in Boullier's eyes, even if neither of his drivers in Kimi Raikkonen and Romain Grosjean has yet to win.
The Frenchman said: "If you want to perform you need to get your weekend absolutely right.
"The slightest setback can have a very negative effect on your performance over the rest of the weekend.
"We saw it with Kimi in Monaco when he skipped the first session because of a steering issue, and also in Montreal with a hydraulic failure in qualifying.
"Some people say that Formula One has become a lottery, but I don't agree.
"I've found this season quite entertaining and very challenging from an engineering point of view."
It is why Boullier confirms "nothing must be left to chance" when it comes to preparing for a weekend, with the only variable being outside influences.
"You need to prepare for every race as meticulously as possible," added Boullier.
"We've come up with a very strong programme during free practice sessions which allows us to do our homework on the Friday without paying attention to what our opponents are doing.
"This said, there's nothing we can do in case of a change of climatic conditions or technical failure."
Lotus have so far proven themselves to be strong in warm or hot conditions, as was the case in Montreal when temperatures rose considerably on Sunday in contrast to the previous two days for practice and qualifying.
It is one of the reasons why Grosjean secured his highest finish of his F1 career by finishing runner-up to McLaren's Lewis Hamilton.
"We've a good idea now as to the car's strengths and weaknesses, and they are plain to see for everybody," said Boullier, whose Enstone-based team are third in the constructors' championship.
"The car is very good with its tyres in races where the temperature is high, and it seems to be competitive on every single track layout.
"This said, we need to improve our qualifying pace and also the way the car performs when the temperature drops.
"We've some ideas already, and some of them will be implemented in Valencia (for next weekend's European GP) and we'll see how it goes."
