Norbert Haug has pointed out that the changes to F1's scoring system for 2010 are not as radical as has been interpreted by some.

2009 world champion Jenson Button hailed the decision to award race winners 25 instead of 10 points next year.

"It's a great idea," he told BBC Radio 5 live. "It's nice that you get five points over second for winning.

"That's important because we all love winning races. I won six races this year and I got just two more points," said the Briton.

But Haug, who is Mercedes' competition chief, points out to the German news agency SID that the plan actually does not involve a greater reward for winning.

"As before, second place receives 80 per cent of the points of the winner, and third place gets 60 per cent (of the winner's points)," the German said.
