I'm right next to KBOS and you're right in that there was continuous undermeasuring there, I'd say until the New Year this year. Since then, every one of their measurements has matched mine pretty well including the 1.6" measured a couple of weeks ago. Maybe they went with a change of persons/procedures for the beginning of this calendar year?
On another note, the EPS looks amazing. Benchmark mean right there, 2 runs in a row with the most recent run looking even better.
That'll put me at ease for the next 12 hours for a d5 threat, no matter what any of the global OPs show for 18z and 00z tonight
