Example 2-8

I didn't understand that the numbers that appear in this example:
.....
350 227.6 327.6 250 300 250 c
272.4 250 250 227.6 250 200 c
....

At last line In the first paragraph of p. 36, you mentioned:
"....using a control point about 0.6 units from the end point"
But why such numbers 227.6, 272.4, 172.4, 327.6 appear?

Example 1-19

The example provides
/UserUnit 2.0 % 144 units/inch (2 * 72)

That should actually be
/UserUnit 2.0 % 36 units/inch (2 * 1/72)
