A zero-delay stress model gives no forecast gain over a line for 22 later PSR J0537-6910 intervals

We test a stress model with no fixed delay for the known glitch size versus next-wait relation in PSR J0537-6910. A model with decreasing loading rate gives T=A log(1+s/B). We fit its two parameters to 44 RXTE intervals and test them on 22 later NICER intervals. Its RMS forecast error is 23.63 days. A line with a free intercept gives 21.46 days. The curved model has 21.3 percent more mean squared error. Block resampling of both training and test data gives 95 percent error-difference ranges that include zero for block lengths of one, two and four. Small-event cuts and date perturbations retain the measured ordering. Numerical integration checks the stress solution. The tested curved law gives no forecast gain, but this small test does not establish a physical delay or exclude other loading laws. No new glitch or planet is reported. Source tables and derivative event lists stay outside this baseline package. Code, model curves, aggregate results, exact source hashes and a retrieval method are included.
