Hi all, Pika here.
It has been known for a while that the No R and No MT leaderboards are not accurate: a lot of old times are not included, and this issue has been bothering some people, including me, not exactly a fan of inaccurate charts. The issue was not regarding only old times, but new times as well: most of the displayed Best Know Times were, in fact, not the actual BKTs.
So a couple of days ago, I decided to fix this issue... and I did.
More than a thousand runs have been added to the charts!
I highly recommend to check the rank of your previously-submitted runs, because they are 100% different.
Here is every source used to add these runs:

I have added the times in a specific way, so that an accurate WR History can be built.
That being said, there probably are a couple more runs that we are not aware of: in the Nsider Forums, which have been deleted in 2007, a couple of threads for No MT and No R times were made, however I do not possess any archive or backup of that thread. So, if you have some kind of source for these threads, please let me know, so that I can add the still missing runs!

And from Pika that's all! Have fun with the newly accurate leaderboards!
