The phrase "are most robust when" is correct and usable in written English.
It can be used to describe conditions or situations under which something is at its strongest or most effective.
Example: "The results of the experiment are most robust when conducted under controlled conditions."
Alternatives: "are strongest when" or "are most effective when".
We identify which learners and which data sampling techniques are most robust when confronted with noisy and imbalanced data.
Body mass reconstructions of extinct vertebrates are most robust when complete to near-complete skeletons allow the reconstruction of either physical or digital models.
Body mass reconstructions of extinct dinosaurs are most robust when complete to near-complete skeletons allow realistic physical or digital models to be produced [3] [7].
Direct ties between physiological markers and phenotypic outcomes are most robust when they are measured in the same environment, but some general patterns can be linked across environments such as predicting the risk of disease (heart arrhythmia) from a genotype's metabolic or expression profile.
Studies since suggest that the benefits of hormone replacement appear to be most robust when the practice is applied as soon after menopause as possible.
"Mind games have no place in our grown relationships, yet eroticism is most robust when you allow yourselves to play with each other in ways that you otherwise wouldn't in your day-to-day lives.

The methodology is most robust when the fluorescence lifetimes of dyes used vary considerably (4 5 ns difference in the example shown in Ref. (13)).
Although the predictive ability of markers is most robust when their expression can be considered as continuous variables [ 24], categorizing the Shc scores into groups with high and low risk of relapse despite tamoxifen therapy is useful for comparing RFS curves.
Moreover, while localization of the mRNA is important, the expression pattern of TrkB protein was not known for those stages of early development when dendritogenesis is most robust.
Estimation of wood volume from airborne LiDAR was most robust (R2 = 0.92, RMSE = 50.79 m3 ha−1) when trained and tested with the 1 ha experimental plot data.
