Random Question Thread (FFXI Related)

Stupid question I know but it always got me curious.
Why is Chocobo movement speed coded in a different way from players' movement speed?
Chocobo default speed is coded at "-20%" but corresponds more or less to players movement speed "60%" (which is the maximum you can achieve).

What reason could they had to use two different means to handle movement speed on Chocobo and Players?


Only thing that I can think of is that many, many, many years ago players default movement speed was doubled, and afaik the Chocobo one stayed the same during that very old patch.
