Kids, when you grow up you will understand the CDA isn't the QR policy. They don't care about fuel. Have you ever heard about anyone being called at the safety office due to waste fuel? while many pilots are being called there due to unstable approach. With this behave you will end up at safety office. I know you are high qualified and experienced kids ... ooops ... pilots.
This is the reason QR chooses this criteria of burning fuel instead of unstable approach. Wake up!
