Kevin SaucierSlab measuring...my 2 cents:
I've measured several Goudey's and like King, I prefer the metric side. I use a soft plastic ruler or a sewing tape measure to work around the contours of the slab. With a loupe I align the point on the tape measure perfectly to the cards edge. Three readings are made (top, middle, bottom) side to side and top to bottom. This will let me know if there are any variances as frequently seen in a micro-trimmed card and usually not detectible by the naked eye. As an example; the top can measure 72mm, the middle 71.5mm and the bottom 71mm, this would indicate a potenital problem. Although not necessarily trimmed, IMHO anything less than 72mm x 59mm is suspect.
