Does anybody out there know his the Gov virus trend data is calibrated?

It still shows us better that Italy & even France when most independent analysis reports us worse than all but Spain for many days

I know they are excluding 1st 50 deaths to improve optics of our relative position when most independent analysis starts at 10 deaths & we look worse

But this can’t explain all of how they get to their trend showing us as better

Are they also manipulating the timeline?

Are they also manipulating the timeline & instead of using the recognised 14 day delay to Italy

Are they stretching this to 17 or 18 days therefore falsely comparing e.g. UK day 20 with Italy day 23 making us look better than we are?
