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.
incidentally feels better here than accidentally or inadvertantly
