Any seeding system is inherently statistical and prone to fluctuations in teams' performance. Many variations on the seeding system are clearly possible, each of which comes with a tradeoff such as higher subjectivity and requiring finer-grained reporting of tournament results and team compositions.

The Ohio Valley Region therefore validates the OVR Juniors' Seeding System each year, comparing seeding positions from the current season versus empirical data observed for the Ohio Valley Region-Molten® National Bid Qualifier. The sole purpose of this tournament is to earn a spot at the USA Junior Olympic Girls' Volleyball Championships. Consequently, the importance of fair seeding is arguably highest for this tournament, and teams are expected to bring their strongest rosters.
