I know what he said. I'm the one that quoted him. That's certainly one way to look at it. Of course is supposition. From the evidence the ship was shaking which is indicative of field fluctuations. The timing of the Tom's statement is questionable because of cut scenes. Bingo warp field instability The computers said nearing. and I never said that the warp core had to be reason why it merely was one of the possibilities thus it doesn't have to be explicitly stated to be true. Your case is well made but it's still circumstantial and just doesn't come close to nailing the Warp 9.975 as unattainable for the class itself. The writers just don't think of everything, I have to make room for their error aswell. If they were infallible I'd be with on this one. hmmm. I'm just the opposite. I think Voyager was developed for the DMZ and the Cardassian Border. Fast, powerful and agile and with an effective sensor range that could cover 15 lightyears. But we'll likely never find out for sure on Voyagers true speed or it's primary use.
