Michael Schumacher has criticised Formula One's new points system for failing to reward his race-winning exploits this season.
Schumacher claimed his fourth Grand Prix victory of the season in Canada on Sunday to move ahead of McLaren's Kimi Raikkonen in the drivers' standings.
But he is irritated that he now leads the Finn by just three points, even though Raikkonen has won only one of the eight races so far this year.
"It's obviously good - and strange at the same time," said Schumacher after taking his career points tally to 999 with his 68th win.
"If you imagine that one wins one race and the other wins four races and there's only three points difference you think whether that's right or wrong. I'm probably not so pleased with it."
Ferrari president Luca di Montezemolo has backed his driver and described the current points system as "absurd".
Michael did a great job of controlling the race despite brake wear problems right from the early stages
"In Canada, Michael truly demonstrated one more time that he is simply the best.
"To go top of the championship was important in spite of this absurd points system. Schumacher only has a small advantage at the top of the table despite winning four races to Kimi Raikkonen's one."
Schumacher was relieved to hold off brother Ralf's Williams in Montreal after taking advantage of Ferrari's slightly heavier race fuel load to move into the lead after the pitstops.
"That was the ideal result. It was a tight and tough race and I wasn't able to push all the way through and drove the pace I needed to," the world champion said.
"We had just a bit more fuel and that's what got us the win. I opened the gap in the pit-stop windows.
"It is always good to go into the championship lead but I think it will be a tough fight to the end."
Ferrari technical chief Ross Brawn said it was one of the best Grands Prix he had ever witnessed.
Ferrari 85 points
"I am delighted with Michael's win. He did a great job of controlling the race despite brake wear problems right from the early stages," said Brawn.
"We breathed a sigh of relief when we got to the chequered flag. The strategy worked well, but the deciding factor was the way Michael drove."
Ferrari sporting director Jean Todt warned his team not to get carried away with being on top of the standings.
"We have reached the halfway point of the season, leading both championships," said Todt.
"We can expect the second half of the season to be very tough because the opposition is very strong.
"We think we have all the elements in place to reach the targets we set ourselves at the start of the year."
