Final T Number

1. Use DT when it is clear-cut and representative.

2. Use PT only when DT is not clear-cut and representative, and PT is.

–Often happens with Shear DT estimates (Shear DT often too high).

–Remember that the Data T is often calculated, so it may be unrealistic.

3. Use MET only when PT and DT are not clear-cut and representative.

–Thumb-rule: PT is NOT clear cut when you have difficulty distinguishing amongst three different PT pictograms along the horizontal.

–Example: on Vis PT diagram, you honestly have difficulty telling the difference between an “A4.0”, “A5.0”, and “A6.0”
