I am not an ultimate Trekkie by any stretch, but I don't recall them dong over warp 10, what movie or episode did that occur?
That why they call it Science FICTION ;)

The 3-part finale, “All Good Things.” Riker orders the Enterprise to go to Warp 13. But in “The Changeling,” Nomad creates a weapon capable of firing on the Enterprise at Warp 15 (note this is warp, not trans-warp which would need an entirely different gauge).
In “That which survives” the Enterprise is sabatoged and makes Warp 14.1 before Scotty shuts her down.
There are others but warp theory, within the science of Star Trek, says Warp 10 is infinity.
