I've just run the 1000 25-pt-matches through XG 1-ply luck analysis.
Analysis of one match takes approx. 6 seconds on my PC.
Standard deviation of match results reduces from a little less than 50% for the raw results to comfortably less than 5%. Thus one VR match is worth more than 100 non-VR matches.
Given the 1000 VR matches, a 1%-wide interval can be given which contains the real winning chance of Gnubg with very high confidence.
The corresponding interval for Elo difference would be about 7 points, or, equivalently by rule of thumb, approximately 0.2 for the PR difference.
