Standing orders for CPA / TCPA

This is from the Golden Ray’s Bridge Standing Orders wrt traffic closest point of approach (CPA).

New third mate’s in traffic often don’t differentiate between crossing ahead / astern in traffic. I never was able to figure out how to communicate this succinctly enough in writing. This table is good way to do it.

Having the time to CPA (TCPA) is also valuable which is mentioned but a time in minutes is not mentioned, we used 18 minutes.
