Historically, quite a few languages were (or are) vigesimal. Perhaps decimal is also unnatural.
It's been at least eight score since vigesimal usage was common in English.
It's still used for numbers between 70-99 in French, which is maddening when trying to copy down a phone number as a non-native speaker.
