Steve:
slice of the table in (1) with a Row filter condition that excludes all but the one row for the current user.
So initial Value formula USEREMAIL() will fill rows of the Table1 with User Id as User Email. So if you have 3000 users that open the detail view in 3 then Table 1 will have 3000 rows (records added). Guess that is the way how it works. And the filter condition should be USEREMAIL().
