I spoke about the best results. They are published each year in the form of league tables. Pretty easy to find if you disagree with my statement.
As for Ofsted - can you explain why you think they know better? They have come under much criticism from the government for making statements that were pretty wide of the mark when grading schools.
So you haven't even given me any examples, great. I would imagine that Ofsted who have much more experience with schools, even considering their mistakes are much more knowledgeable than you about the subject.
If we wanted to increase school results, we could just simply increase school budgets and stop decreasing them. I know schools and colleges that have had to reduce lessons due to lack of funds.
