I know 10 is called "sof hacheshbon" because we do base-ten arithmetic.
And this is, al pi Google, the most discussed usage.

However, couldn't the Ramban simply mean that the seventh was the end
of what the satan's cheshbon for what he was doing to Iyov? As in
the completeness of sheva - shavua - sova (- shevua?).

:-)BBii!
