For Belgium, the official source shows 237 Teslas but doesn't show the S/X/3 split. Ev-sales.blogspot.com shows 26/14/197 for S/X/3. The total is 237 but the data source for the split is unknown. It's up to
@hobbes.
By the way, the sheet is designed in such a way that if two entries are approved for the same country/month, the latter takes effect even if it's an estimate. For example, for Belgium/January 2019, we already have the official number approved. Now there is a new entry for Belgium/January 2019 with the source as ev-sales.blogspot.com. If this is approved, it will override the previously approved entry.
Btw,
@mrdoubleb, for Switzerland, the excel file by model shows YTD and previous months need to be subtracted. However, the excel file by brand already shows this month's number.
@hobbes, there was no data for Portugal in 2018. Therefore it was not included in the top 13. In 2017 Portugal was #19 in Europe. However, the number for February is going to be released soon and I have seen some news that it's going to be high and they could be #7 or #8 based on the first two months. We can look into this when the number is out.
@Steve m, it's fixed now. There is a formula that splits Tesla numbers into S/X/3 automatically but it needed a minor change to work again.
