Japanese monks and emperors kept meticulous records of cherry blossom festivals for 1,200 years. They accidentally built the world's longest climate dataset

It’s there a difference in tone or meaning between accidentally and inadvertently? I feel like accidentally means they did something that was a bad thing.
Mr Bob Ross would like a word…
I agree with you on inadvertently, but accident, if I’m not mistaken would generally considered something where you do not inherently attribute blame. At least thats what I recall being justification for making the change in UK in calling traffic ‘incidents’ incidents instead of accidents several years back. Dunno if it stuck though.
Interesting. Although I still maintain that accident bears a negative connotation, even though blame isn’t necessarily a factor. As if the outcome was a negative thing, rather than a positive, as in this case.
