Obtaining VRR data from XG - Problems

In Response To: VRR - Challenge (Rick Janowski)

The following example appears to show that obtaining VRR data from XG can be problematic:

Note that I have computed the Weighted Averages column from the tabulated information for each match length.

There seems to be two ways of obtaining the VR Elo Rating, although they are fairly close.

With regard to obtaining the VR Win Rate, there appear to be 2 or 3 ways (I am not sure about VRWR(2)). It seems obvious that there is a major bug, because these results are very inconsistent and it seems inconceivable that the expected long-term win rate for a player with a 2 PR edge cannot be 45%!

Can the "PR Crowd" please clarify how the VRR and VRWR should be obtained correctly from this profile tab and comment on any inconsistencies.
