You still did not have a look at the link to a previous discussion.
There is explained about the same you write here.

Hi,

I Agree that using AAdd is a lot slower than sizing the array when
creating it. All I'm saying is that counting the records can be an
even more time consuming operation. It all depends on how it's done.

In Dicks first message he talks about 622 records. I would say that
using AAdd is fast enough in that situation.

Now, counting the records is not critical for avoiding AAdd. You could
expand the array in chunks of 100 records at a time if you like and
set the exact size when all records have been added. This way you
could loose very little time for expanding the array while avoiding
counting the records at the same time.
