Previously, the most recent available data only covered until December 2021. Traditionally, many industry participants rely on the EIA-923 "consumed and received" method to estimate ongoing inventory levels. However, this method has been shown to produce significant variances at the plant level, rendering it unreliable for precise inventory tracking.
The newly released EIA data allows us to definitively demonstrate the superior accuracy of Vulcan's volume calculations compared to the EIA-923 methodology.
Ideally, after incorporating the update, the adjustments required for normalization should decrease, signifying convergence with Vulcan's calculations. This is precisely what we observe: the average adjustment factor has decreased from 0.9 to 0.95, with 1 representing a perfect match.
In simpler terms, using Vulcan delivers significantly more accurate plant-level data compared to the EIA-923 "consumed and received" method.
