Should we add milliseconds to the timing? Most single level categories are as low as they can be, but with milliseconds there won't be as many tied world records.

I don't think we should add them since not many people are still running this and it doesn't have that too much runs to say that MS makes a huge diff and that it can't stay without it. It's not like the SMB speedrun pg which can't stay without MS.

There's nothing wrong with ties, and as lag is a thing using milliseconds is definitely a bad idea with the current timing. In terms of timing for ILs I do still definitely think IGT would be better though, for reasons I've described before (I have a thread about it).
