The UPS has the same Latitude scale ( NM per inch ) at 10 degrees north and at 50 degrees north. A Mercator chart does not.

That's true, if you want to make a chart that covers the entire range from 10 to 50 degrees, but if you just want to make a small area plotting sheet covering 10 to 11 degrees or 49 to 50 degrees then each of those separate small area plotting sheets will have constant scales.
