Your fit is quite unconventional.

Most people find that their hips rock when their knees extend that much, causing chafing and making it very difficult to pedal smoothly and quickly. Since you really are fully extending your knees, you can disregard the entire concept of KOPS because you won't achieve it unless you have a 90 degree seatpost.

I would suggest that you would find a time trial bike to be much more comfortable and suitable to your preferred riding position.
