Those ranges of impedances are basically worthless.
I don't agree :-)
If I had to test such a tuner the first thing I would do
is put a pure resistor of those values and try to
match them accross the frequency and power range announced.
Measuring the insertion loss would be nice too.
Of course it is not the complete story but a good start.

Which basically tells you nothing about the ability to match a complex
load.

I measured the impdance of a vertical to be well under the specified
limits of the LDG tuner I own. However, it fails to get a match on
160 M and 17 M.

The SGC tuner has no problems getting a match.
