Thanks for taking the time to post your thoughts. The UK rules about STARs changed recently
3.2.4.1
(d) (iii) If following a STAR, after the 7 minute period... arrange descent as close as possible to the published descent planning profile.
I am not saying you are wrong, but you may be less "right" than some other answers!! (In truth I don't know if there is a right answer, especially if you take into account what level you will want to be at to fly an approach starting at LAM).
Any other thoughts?
All the best
