In 2022, I bought a Pro38 I540 advertised as an I540-16A White Thunder. I'm silly for just noticing this now, but the packaging I received says it's an I540-15A White Thunder. The QR code instructions point me to instructions that list 15 seconds as the maximum delay time:
But my packaging and this table are the only places I see that state a max delay time of 15 seconds (vs. 16 seconds). The vendor website I bought it from (Apogee) says 16 seconds. The Pro38 website product lists 634I540-16A (and no 634I540-15A). Thrustcurve.org does not list a 15-second delay time as an option for this motor (it lists 16, 13, etc., seconds). Long story short, I cannot find ANY reference to a maximum delay time of 15 seconds anywhere except on the packaging and in the linked instructions.
Has anyone seen a discrepancy like this? Apogee is a large reputable company so I doubt this is "fake"... right? My rocket has an optimum delay time of 16.5 seconds in sims, so I'd really prefer 16 vs. 15 seconds.
