What is the Accuracy Specification for PST Values Outside the Range of 1?

It is not necessary to specify the accuracy for PST values outside the range of 1.0, as any value larger than 1.0 is non-standard. 

The standard (IEC 61000-3-3) requires that the value of the short-term light flicker severity index PST
1.0. For the WT3000 with the /FL measurement option, the accuracy specification for PST is ±5% when PST=1.
