Its not about the documentation, its about the complexity and subjectivity (e.g. substitute goods, weighting of regions, remove outliers, and quality adjustments). I'd much prefer a simpler "less accurate" measure like the change of a fixed basket of goods from two periods within a short time period and an updated basket to be used for the next period. That way you're not stuck w/ buggy whips on your CPI index. Instead we have an indiscernible mess that doesn't reflect reality and that no one trusts. https://www.bls.gov/opub/hom/cpi/calculation.htm https://www.bls.gov/opub/hom/cpi/calculation.htm
