I hope I have this correct. Your LAN for yesterday (September 28) was at 16:42:10.4 GMT.
I've started shooting the Sun about 30 minutes before MP and then waiting for the Sun to descend to the same Hs figures recorded before MP. Using the method mentioned in Bowditch the several results are averaged based on equal Hs and time. The results I'm getting are a few seconds within calculated MP. The clouds being cooperative, of course.
