You have hit the nail on the head there. You can actually hear the PNF's brain ticking over as you ask them to clarify what position they are giving an ETA for. Usually after an awkward pause you hear the other voice on the flightdeck meekly explain what's actually going on.
I just wish they were honest from the beginning. Feel free to give me the time the GPS/FMC says for the "Foxtrot" waypoint but at least tell me that's what it is.... five miles away is not "The Circuit." Also when you start tracking for a 15 mile final RNAV approach please update your ETA because I'm pretty sure it's going to be different from the one you gave me when you were tracking direct to the airport......
