Here are the very preliminary results of the analysis comparing US based RNGs (REGs) with European based RNGs around Dec. 31 23:00 UTC (midnight in Netherlands, Germany and Switzerland).

The bad news: The predicted difference in variance during the first minute after midnight (with 1 sec time resolution) couldn't be confirmed  (see graph below for the plot of cumulative chi2).

However: There appears to be a difference developing during the last 5 minutes of the European year due to first an increase in variance in he US-RNG's followed about 60 seconds later by an increase in variance in the Europeans. Furthermore there is a sudden drop in variance of the European RNG's in the second minute after midnight which is recovered in mins 3, 4 and 5. (see graph below which covers the 10 minutes around midnight)

So this runs again against my hypothesis (i.e. there is no notable extra variance in the US - RNG's during the first minute of their new year). However during the 5 minutes preceding this moment the European RNG's are increasing strongly like the US RNG's were doing before europes new year. Then at midnight the cumulative chi-squares come together agian and stay close till minute +03:30 at which point the europeans take off again. I also looked at the correlation between the compound scores within each minute and found no systematic behaviour. Most correlations are negative and the over-all correlation (over 10 minutes) is -0.065 (p = 0.11 two-tailed).
