Does the Administer CiviCRM → Mailer Settings effect both the basic send mail to selected records and CiviMail ?

Mailer Spool Period - 180
Number of seconds between delivery attempts for new outbound mailings

Is this 180 seconds (3 minutes) for each email or for each batch of emails?  Seems like a long time for each individual email, but not very long for each batch.  What type of setting are others using here and what does it mean.

Mailer Batch Limit - 0
Throttle email delivery by setting the maximum number of emails sent during each CiviMail run (0 = unlimited).   Is this the number in each batch set above or the total emails requested to be sent?

Mail Spool Limit - blank
Set the limit of emails sent via smtp mailer, for more than limit send them in Spool table

Any examples.

I have 4 email addresses for myself - so sending - with above with
http://<your drupal site>/civicrm/mailing/queue?reset=1
sends all 4 emails immediately

Changing to
Mailer Batch Limit = 2
Mail Spool Limit = 3 or 4

Processes 2 first time and 2 with 2nd url request

Changing to
Mailer Batch Limit= 2
Mail Spool Limit = 1

Processes 2 first time, 1 with 2nd url request and stays running with no more emails even when requested.

Don't do new civicrm cycle, but just change mail Spool Limit to 2
Does send one remaining email.

Does not seem like the 180 second setting has any effect when I process by url (no cron job running).

Sorry, I have to ask.  If the cron job is set to every 15 minutes and the mailer spooler interval is set to 180 seconds (3 minutes), is the next spooled batch going to run only once every 15 minutes anyway, when the cron job calls the spooler?

Let's say that we have 1,200 emails to send and some flexibility on how long.  Would we be better sending 100 once per hour or 25 every 15 minutes or 5 every 3 minutes?  What are other's doing?

How resource intensive is just the act of running the cron job?  I know it checks settings and sends an email that it ran.  I guess I have to start someplace, so I picked running every 10 minutes and sending 20 emails in a batch.  So this gives 120 emails an hour and half a day to process our whole list - does this sound reasonable?
