Better pretraining yields better robot policies, robust even with sparse post-training data

A robotics research finding: better pre-training produces better robot policies, and the gains extend beyond headline performance — policies pretrained more thoroughly remain more robust when robot post-training data is sparse. The sharer highlights that the study's plot tracks actual task completion rate rather than vague metrics like 'improvement over baseline.'
