But warp factors are a completely different ballgame entirely. There's nothing to even work from since even on-screen goes at speed of plot (see ENT for numerous examples).
Let's not pick on ENT; the problem goes back as far as TOS. "That Which Survives" asserted that the ship could cover 990.7 light-years in 11.33 hours at warp 8. That's about 766,000
c, but warp 8 is supposed to be 512
c. So the stated warp velocity is about 1500 times higher than the published scale alleged it to be.
Not to mention that a velocity of roughly 2000 light-years per day would've allowed
Voyager to get home from the Caretaker's array in about five weeks.
This is interesting-slash-worrying.
I just came up with what I think is a great idea for a DS9-R story yesterday, set post-The Soul Key and following up on certain aspects of that book. So are you saying that I wouldn't be permitted to submit it as a pitch, because it's based on DS9-R and not DS9-original?
The guidelines are for beginners just starting out. You have to prove you can follow the rules. Anything you pitch through that process is essentially a "demo tape." You're showing what you can do. You're selling yourself more than you're selling any single story. Once you've proven yourself to an editor, that's when you can try pitching a broader range of ideas to them.
However, something like DS9-R is generally going to be an editor-down process -- the editor is the "showrunner" with a plan for where the series is going, and will select authors to participate in advancing that plan. The selected author will probably get to develop a plot idea of his or her own, but one that incorporates the editor's plans for the next phase of the story in terms of where the characters and overall situation are heading.
Of course, with the editorship up in the air, there may not be a firm plan at the moment. But whoever does get the DS9 gig, if they decide to follow up on the state of affairs in
The Soul Key, would probably select an established author to handle it. If you're just starting out and trying to break in, you don't want to try for a continuity-heavy ongoing series. Yes, several people have gotten their professional debuts in series like DS9-R and SCE, but that was at the invitation of editors who'd decided to give them a try after gaining some acquaintance with their writing skills through other avenues.
