No emotive heat from my side, all pretty clear logic.

But no shortage of investment from my side either.

I agree, it should all be simple. In theory. In practice, maybe not.

Area and formulas are great things - when they are used correctly and when they work.

Above is a good example. Take it as just that. Not more.

As we knew from our fin matrix project (itself just a series of factors, variables and formulae),
to do it properly truly is a complex or daunting task.

An accurate fin formula would indeed be a welcome attribute ~ for all of us.

So yeah, let's go for it. Who's up for the challenge ?

Cheers ~ Ian
