Translation Notes

Nobi ノビ

Late life on a pitch. Fastball Life 4 is ノビ 4 in the Japanese Power Pros, so I kept the translation consistent with that.--Odawali 01:11, 2 May 2008 (CDT)

Kyusoku 球速

Velocity. I think this refers to the raw speed ie at the point of release. Speed change seems to be governed by the Late Life parameter--Odawali 01:11, 2 May 2008 (CDT)

___Kei 系

"System" is the scientific translation (as in "isolated system" etc) for the standalone term Kei; it's more frequently used after a word to denote family/type.--Odawali 01:11, 2 May 2008 (CDT)
