Very good, thanks.
We each have our favourite types of puzzles, and sometimes solvers (just like cryptic crossword solvers) need some insights to help to solve fairly short sequences.
You can always repost similar sequences in the future and change the algorithm very slightly. At that point you may have many people who are surprised by how much they have learnt and that your enigmas are far too... easy! :-)
Hope you're feeling better.
I do :) Thx
