Yesterday there was someone under the name of Fun@Royal. He drove two impossible first dedi's. Sure of this, because he drove a first cp on Ivy-BM-19-PoleDancing#3 that was one and a half second faster than the rest, while it was just a straight road. The other track was a stairs track. Both dedi's were like 10% faster than the second ones, driven by FunnyBear.
I also specced him and he was going awfully fast.
I have a screenshot if you would like to see the first cp time on the ivy track.
