Never mention numbers in regards to sci-fi, fantasy or comics. It will always lead to nerds deraling the conversation and debating the accuracy.

Case in point: The "Enterprise" is the name of multiple ships that have max warp capabilities ranging from ~7 or less to way above 9.9. (The warp scale is different depending on the setting, but in general it's logarithimic with 1 basically being light speed and 10 being instant travel to the point of seeming like teleportation. So once you go past 9.9 it starts getting exponetially faster, at alarming rates.)
