Hi Prasun,
Ratio only masquerades as a technical term. It's whatever it takes to convince the other guy to set up settlement-free peering and you'll tweak your routing adjusting reality to match. The information in peeringdb is just a rough guide to help you figure out who to talk to as you try to adjust your traffic profile so that you can go after the big fish as "balanced."
