Candidate strategy

Typical Auto-design directions for v-belt drive — compare light, balanced, and conservative sizing before committing to Validate.

Option	Basis	Pass	Tradeoff
Compact drive	Smallest pitch/section	May require high tension	Small footprint
Standard drive	Catalog service factor	Pass expected	Balanced life and size
Heavy-duty drive	Higher strand/section	High reserve	More cost and inertia
