This looks correct for high. We'll also need to add the case for when the value is less than "low" (for which this is exposed as "critical value").

For optimum:
If value is greater than or equal to low AND value is less than or equal to high then value is "optimal value"
Else, value is "suboptimal value"
Note that in this case, there is no "critical value".

For low:
If value is less than or equal to low, then value is "optimal value"
if value is less than or equal to high (but greater than low), then value is "suboptimal value"
else, value is "critical value"
Also, looks like there is a typo for the word "suboptimal" here.
