To be honest, the window title bar of my acquired game doesn't say anything about version, but the readme.txt says ver_4. Which I believe to be the latest (though DLsite is not a huge help here). Yours?
If you want to apply this to the 03/22 updated game (ver_5), then yes, most definitely.
You will get reverted back to whichever version the PT was based upon - most probably ver_4, from 03/04.
EDIT: Well, it seems the partial is actually based on ver_1 (if the 'Scripts.rvdata' being exactly the same in ver_1 and the partial is any indication, which it probably is), so, from 2/28.
