Hi Jude,
A couple of things. A counterclockwise indicator would be 
nice. Would a digital indicator, zeroed at dead flat, read 
negative so you wouldn't have to subtract from 0.75? Or are 
there digitals switchable to "backward"?

Next is, a compression ridge or two will give you a false 
positive crown reading on a flat or even concave board. Spacer 
feet at the ends of the bar would avoid that.

Then there's the "S" curve crown, which can easily read 
positive within the right 12" span.

But who checks crown anyway, eh? <G>
