Well this is interesting.
Everyone knows LOIO was nerfed to have an xp penalty right? Not so fast.
The earliest reference I'm seeing to LOIO ZEM being 60 is June 2003 ShowEQ forum posts where they were using windbg.exe to pull ZEMs out of the client memory.

Both the above two newsgroup posts actually in-era say the ZEM was 75.
If LOIO ZEM was nerfed to 60 at all, it may have happened outside of the P99 timeline.
