The primary assumption in the Arxiv paper I referenced is that the meteor tracked in a line to the 25' dia hole in the ice
"Assuming that the hole in the ice sheet of Lake Cherbakul was produced by a fragment of the meteoroid is also a very important hypothesis of this work. More importantly, our conclusions relies strongly onto assume that the direction of the trajectory of the fragment responsible for the breaking of the ice sheet in the Lake, is essentially the same as the direction of the parent body." You would think a 50kton blast might knock pieces off track a bit.
