I did the test using the following script, and I found there was two records per page for the first and third extents , but there was only one record per page for the second extent, Why ?
BTW, you can observe that behaviour by insert record one by one and run"dbcc ind([Test1123],t1,-1) " immediately after running " insert into t1 values ('') go 16"
use[Test1123]
go
create table t1(c1 int identity,c2 char(3000))
go
insert into t1 values ('')
go 16
insert into t1 values ('')
go 8
insert into t1 values ('')
go 16
dbcc ind([Test1123],t1,-1)
