For interpreting 40C stored signal data, should I continue to use NRG’s published 40 Consensus Transfer Function (CTF), or should I use the specific wind tunnel, calibration test-derived value (value provided on calibration facility’s test certificate)?

You can use either. Use of the consensus transfer function remains a good choice. It is also acceptable to use the individual wind tunnel measured values provided with the sensor.
