Nope. You might be listening to a 14 minute old observation that’s about to change.
“An actual aerodrome QNH obtained from an approved source is valid for a period of 15 minutes from the time of receipt.”
You would have to regulate that the reduced minima is only available until the end of each quarter hour when you must either get a new forecast, listen to the AERIS (if it covers that aerodrome) again, or ask flightwatch for another update. Easier to just listen to the AWIS and note the time.
Interesting to note an Approved Meteorological Observer isn’t on the list...
