If anything , slightly faster.. that dynamic, IF controlled, can produce a turn which allows for easier collection and also allows the weight transfer and rise to be incorporated into the fwd motion.
A good rule to remember in F/T ( generally ), is the rise is absorbed between the feet and should not be thought of as a Vertical action( it impedes fwd progress if danced with incorrect rising and lowering ) .
The time allocation, if used correctly, should not affect the phrasing . In essence, re-adjusting rhythms and time, are part of a Prof. interpretation ,seen in most comp. dancers.
These concepts need to be taught under the guidance of a seasoned Pro.
