There are 36 nations represented among Euros Ladies according to the entry list, but there are 43 this season as well, because there are two entries for Finland, France, and Sweden and three for Italy and Russia. (The numbering on the entries list is confusing.)
Last season the minimum scores were the same for all senior championships. For Ladies, they were 15 for the SP and 25 for the FS. This year for Euros/4C's they are 20 for the SP and 35 for the FS, which is a considerable jump, especially for the FS, yet the entries are the same, and the ISU didn't raise them to cut the field down to around 30. It looks like all 43 will skate the SP. The only two who have yet to establish both minimums are the two substitutes from Belarus.
