Lighting help and Yield Math.

Well I have decided to go small and work my way up over the next year. Here is my question:

What is the minumum amount of lights you think I can get away with with for 99 plants. I was thinking of 8 600 wall HPS.

My friend does 12 600 watt HPS. He has 105 plants and has yields just over over 12-14 weeks at around 12'ish pounds.

I'm have a hard time figuring out exactly what kind of yields I should get with x amounth of lights and x amount of plants. What is the formula?

Thanks,
