Reminder what the OP wrote, split into the two statements for more clarity:

> must sharecrop at least some of their land, and

> on sharecropped land, extraction rates are on the order of 50

That's not 50%. That's 50% of an unknown number.

And certainly that this statement about a 50% figure on the internet has not come with an absolute value is very important.
