Absolute precision? Have you read any law lately? Legal texts are (to me) surprisingly imprecise. One wonders why we have not developed something explicit like mathematical notations for legal stuff. I mean, comma/and/or separated lists in full text? Not even parenthesis? That’s not precision.
Many legal documents are purposely not pinning themselves down on specifics, because they don't want an agreement circumvented on technicalities, when it should be pretty clear to reasonable people what is intended in an agreement.
