It's not just me. NAR S&T documents significant differences (significant enough that AT had to change the designation to meet the NFPA specs on several of the reload delays. This is a documented FACT, not subject to debate. IIRC all but one of the out of spec delays are SHORT.
Alas, most of the HPR motors, including ALL of the 38mm WL motors I've had with way short delays were tested by TRA TMT, and they keep the results of the delay testing a SECRET. One of these days, there's going to be an accident as a result of one of these inaccurate delays, and TRA *WILL* be named in the lawsuit, and all of their test data subpoenaed. The decade long cover up will end eventually, and it won't be a good day for TRA.
