Jay, I 100% agree.

Choice is our own, want to be a rich engineer or just an engineer.

At times there are solutions to problems which are simple and cost effective and equally reliable in results with complicated applications.

Initially I myself had thought of doing it with tables, but I said to myself that perhaps its not the designers approach. But at the same time that's not a business man's approach, as I now realize.

The crime would be only if I lack in skills of doing it the mathematical way like Wouter suggests.

Yes, I will make spread sheet and cram it into my code :)

Thank you Jay

Regards
