It's maddening but yet it's seldom addressed.
They did try a few times in the 2010's to fix it. Taking away the measurements from the Central Park zookeeper was a good first step. I'm not sure who thought that was a good idea in the first place and why it went on for so long. They then gave it to the Conservancy and they were solid for a couple of years but they don't seem to give a sh!t anymore. I forgot what year it was, maybe 2017/18, NOAA adjusted three Central Park totals at the end of the Winter because they were so egregiously wrong.
I've discussed it with them many times through the years and for a while they listened, but they've worn me down. I now just try to ignore it, but it's hard to when it's the so called official measurement for all of NYC.
