Script is cool. It works well. However it maybe of more use for Extremely large databases/tables. At my system biggest table of 414 million rows in a table with id defined as int identity(1,1) scarcely takes 0.19% .
TableName PercentTakenIdentityValueMaxValue
[dbo].[Entries]0.1928 414052337 2147483648
