# Can these Gifts be used together for a supersonic Swara?

Reading through the W20 Changing Breeds, I realized either the writers overlooked something, I missed something or Swara are ludiciously fast:

Swara can start with Diamon Claws or Impala's Flight (usually a general gift of rank 3)W20CP p.83. The Swara gift list lists Speed of Thought (Level One) and Speed Beyond Thought (Level Three)W20 CB p.90.

Impala's FlightW20CP p.86 does double movement speed for a number of rounds as an (Athletics+Body vs 6) test results.

Speed of ThoughtW20 p.191 plainly doubles movement speed for 1 scene for 1 Gnosis.

Speed beyond ToughtW20 p.193 plainly grants tenfold movement speed for up to 10 hours, but nothing but running can be done. It costs 1 Gnosis.

A Swara can have up to 9 dexterity in feline shape with a 5 dexterity in human shape. This results in $((20+3*9)*2)=97$ yards base running speed. That is including the feline shape multiplier W20 p.296.

With all the three gifts started up, this grants an initial speed of 3760 yards per combat round, till impala's flight runs out, and then 1880 yards (1719.072 m) per round.

Assuming one combat round is 5 seconds (the median between 2 and 10 seconds that are used commonly), this would be a speed of 343.8144 m/s - or Mach 1.01 (and subsequently Mach 2.02 on the Impala's flight turns).

That would mean, with the 5 second turns, that the reach within 8 hours would be 9901.8 km / 6152.7 miles without impala's flight, as long as this run does constitute as a single scene, and with constand access to impala's flight twice that.

For comparison: Direct line from Kairo to Capetown is ca 7250 km, while the shortest land route is around 10500 km.

Question: Is this combination of gifts legit to use and did I calculate the outcoming speed right after that?! Does a Swara of rank 3 travel faster than than sound in atmosphere (depending on combat turn length)?
