For the January sudoku test I have written, I used categories to define the sequence of the puzzles, and also sizes. I don't think it would have been easy to put the puzzles in an increasing-points-order, other than putting just one puzzle per page. But it crossed my mind to do so. Maybe for future tests I will keep it in mind.

In my case the points distribution I had in mind before it was tested was different than the average of all testers showed. But I am not such a quick solver anyway.
