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 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.

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".
