Following the publication of Circular-T nr. 357 we shall take a look at the RMS error of UTC-UTC(k) in different laboratories across the world. Should we rank the 75 laboratories that have complete UTC-UTC(k) records by RMS error for this month we find the following.
Warning: Past performance is not an indicator of future results.
Circular-T 357 RMS Ranking list, top 10 labs Rank Lab (Location) RMS( UTC-UTC(k) ) / ns 1 MIKE (Espoo) 0.524 ns 2 PTB (Braunschweig) 1.056 ns 3 NIST (Boulder) 1.528 ns 4 ORB (Bruxelles) 1.556 ns 5 NPL (Teddington) 1.627 ns 6 NTSC (Lintong) 1.671 ns 7 OP (Paris) 2.090 ns 8 TL (Chung-Li) 2.095 ns 9 USNO (Washington_DC) 2.356 ns 10 SP (Boras) 2.409 ns
It's much easier to be lucky than brilliant, so maybe we have to look one further month back and do the same thing for Circular T 356:

For completeness, here is the whole list for Circular-T nr. 357:
