When I test I never go right to the limit. Only because when you are below the limit you can go at the same speed all day, and that's the only way you can be absolutely sure about what you are testing.
I always work the same way, starting from the beginning of the weekend, so I know at the beginning of the race, from all that I have analysed during the practice, whether I will win the race or not.
I have no problem with the people who work hard to get success. But I think people are very jealous about success. I work very hard and they don't appreciate that.
