It makes no real difference whether Q's chainmail obstacle was close to Deneb IV or far away from it, or perhaps in orbit around Deneb. What matters is that the combined ship thereafter flies in the opposite direction at truly extreme warp, spending at least several minutes doing so (all the onscreen moments plus the time it necessarily takes to move those people to the saucer, plus whatever optional extra one wants to add to make it more realistic).
As per the math done upthread, this is at least a lightday's worth of travel (in terms of onscreen dialogue - backstage sources would indicate at least doubled figures over what Riker claims in "Bloodlines"), and probably at least one order of magnitude more. After all, one lightday is what we get from warp 9 and the E-D was actually fleeing at warp 9.5 (and possibly attempting even higher speeds, at acknowledged extreme risk, because Q was moving faster than that yet didn't catch up).
So the saucer compensated for the combined ship's multi-minute travel at point-two-warp-factors-past-redline-at-least speeds in only a few extra hours. That's pretty remarkable in any terms, and doesn't fit with the idea of sublight travel at all unless we disregard onscreen evidence on one issue or another.
