@slyfox,

Add an index column in your table in Query Editor of Power BI Desktop.

Then create the following columns in your table.

Column = CALCULATE(FIRSTNONBLANK(Table[Type],1),FILTER(Table,Table[Index]=EARLIER(Table[Index])+1))

Changes = IF(Table[Type]=Table[Column] || ISBLANK(Table[Column]),BLANK(),CONCATENATE(Table[Type],Table[Column]))

Number Of times = CALCULATE(COUNTA(Table[Changes]),ALLSELECTED(Table[Index]))
