Actually the example in the User Guide (Figure 7) does limit LK to
50%; that's the part that I deviate from the User Guide.

Actually it doesn't matter.  At 100% overall ink limit, 100% LK
matches 25% MK.

If the overall ink limit is reduced to 70%, the maximum LK is reduced
to 70% of its previous value, and 25% MK is also reduced to 70% of its
previous value.  The two still match.

In subsequent tests, I keep the overall ink limit at 100% but limit MK
to 70%.  In that case, matching of LK will have to be done relative to
100% MK scale, not the reduced MK scale.
