Based on their original article on rating:
The bell curve distribution of player ratings was also adjusted to be centered on a mean of 1.0 with statistical deviations about the same as other popular rating systems like HLTV's 2.0 rating for CS:GO. That should make it relatively easy for FPS fans to get a rough judgment on whether a rating is “good” since it is a familiar quantity.
So it can't be THAT much off but that wasn't the point of what I wrote. It was the rating consistency over more rounds played. Let's say that the HLTV rating is qual to the VLR rating in this case. Donk has still played double the rounds of Aspas through the years.
