I think We can use average column a + average column (estimating), because
of VARCHAR2 in our table, then we determine can determine how many records
inside our database.
I think we can not ignore the overhead bit inside our tablespace, my Guru
said leave 1 row space between PCT_USED and PCT_FREE I forgot to ask why.
Sorry I am not good enough to help you, I have to go find my old notes....
sorry.

Dear Listers,
I've download a presentation talking about Calculating PCT_USED .
the formula is quite simple :
PCT_USED + PCT_FREE < 100
PCT_USED = PCT_FREE + 1 row size
but I have no idea to calculate the size of 1 row in a table .
is there anyone who knows to calculate it ?
or any alternative formula to calculate PCT_USED ?
Thanks a lot in advance : )
