Article: “Better predictions of the working life of industrial components”

“A minor disparity between an established mathematical model to predict creep crack growth behavior in materials in high-temperature environments and actual data has prompted Dr. Warwick Payten to reassess the approach and revise the model.”

“Being able to more accurately predict crack growth in real components is highly useful because it allows you to potentially extend the life of operating industrial plants and conventional, solar and nuclear power stations with confidence,” said Payten, a senior nuclear fuel cycle researcher.”

The mathematical model in this case has “changed” and the improvements have shown “progress.” Take a close look at the RLE to see what exactly is the difference between change and progress.
