Zero yesterday and zero today. I continue to perturbate the clues in the Royle's list searching a new one "between" 2 known grids in the minlex form.

Thanks for stimulation Jean-Pierre is your search within an interval random or complete? if complete then you can identify intervals that contain no 17s have any such intervals been identified yet?

I limited the search depending on the statistics for all the Royle's grids : less than 5 clues in a row, column or box and less than 5 empty groups (row, column or box). Maybe the sixteen clue sudoku is weird. Here in Quebec, it is always raining this summer, I have time to continue searching.
