Should there be a split between the consoles to account for different hardware?

No point as of yet. I'm the only one that doesn't use PS2. Maybe in the future if other consoles become used.

Due to a new Xbox 360 run being submitted, I have learned about this version and its differences form the other console versions. Because of this, I believe a separate category for Xbox 360 makes sense. As of right now however, the PS2 and Wii versions are not different enough to my knowledge to separate those.

It seems like the PS2 version loses a few seconds to the Wii version due to the Wii version being able to skip through the beginning faster, whereas on the PS2 version there is a bit of delay between selecting Restart and the start of the next game loading. I would suggest to either split between PS2 and Wii or change the timing method to begin timing when the new game loads in.

I see your point. I can change it to make the starting time when the game loads in.
