Thoughts on scale

When I started drawing, I used metric scale. Nothing but normal for an European. But quickly I feel that recalculating all North American sources would be difficult. So I switched to a scale of 10 computer-points equalling 1 foot. Not so bad, except for very small details. Converting inch to decimal feet is not always easy. Rounding up or down the figures creates sometimes small gaps. 

During last weeks, I recieved many very fine documents. They will permitting me to draw details of unthinkable precision. So I consider to switch to 1 computer-point equalling 1 inch, or 1 foot = 12 points. Older drawings could be reused after scaling up to 120 percent.
