“Eton Systems' Unit Production System "can boost production efficiency by 30-100%"”

No 30-100% figure — or any percentage — appears anywhere in the Eton Systems garments page, which is the only source provided. The page discusses efficiency gains from its overhead conveyor system in purely qualitative terms (less manual handling, more sewing time, no wasted transport) and never uses the term "Unit Production System" or quantifies a productivity uplift. The sources discuss the subject but do not settle the number.
