Still, both previous years were notably up after the first month already. This is different and perhaps notable regardless. Either the release schedule is skewed forward or the hardware is genuinely stagnating. Or perhaps the benchmark is hitting some other CPU unrelated bottleneck.
They have more than twice as many samples on their Feb 10 update this year (47810) as they did last year on Feb 14 (22761). They have shown some growth year on year in sample size, but nowhere near doubling.
That suggests this month has been an outlier in having a strangely large number of samples already, which could all be related—maybe their software started being bundled with a specific OEM or was featured on a popular content creator or whatever.
As a sibling notes, less accurate just means less accurate, not necessarily skewed upward. There simply is less data to draw conclusions on than there will be later, so any medium-sized effect that adds 20k extra samples will have a larger effect now than later.
Just because the error isn't presented the same here doesn't mean it's error free...
