So once again. That source is not the full month. It is unclear if the last days are then added to the next month or not. Might differ from brand to brand.I see no figures yet for NL and Belgium. But Sweden already reported :
April 2015 : 75 (2014 was 21)
YTD 2015 : 213 (2014 was 53)
The previous Q1 total I had for Sweden + 75 did add up to more than 213. Looking back the March report now mentions 138 for Q1.
