I don't understand why we are stressing the importance of physical
accuracy in projections. Do people expect units to measure as spec'd
when projected?

When I think of computer projections I think of PowerPoint, and I
expect my font measurements to behave as in PowerPoint. When we spec
12pt on PowerPoint does it result in 12pt type on the projection
screen which looks like a tiny dot 15 ft away? No.
