Known ambiguity
The Google Drive replacement spreadsheet contains a CM100G entry while the supplied catalogue table shows CM110G. The live product table follows the catalogue and records the Drive mismatch instead of changing the source model code.
Several medium-pressure GPV rows use repeated or alternative power entries. They are reproduced and flagged for quotation review.
