Host Check Clarification

Looking for some clarification on Nagios Host checking.  I am monitoring the
SSH service on multiple hosts, from what I understand when the SSH service
check has problems, Nagios then tries to do a Host check.  
 
>From the documentation
"One instance where Nagios checks the status of a host is when a service
check results in a non-OK status. Nagios checks the host to decide whether
or not the host is up, down, or unreachable. If the first host check returns
a non-OK state, Nagios will keep pounding out checks of the host until
either (a) the maximum number of host checks (specified by the max_attempts
option in the host definition) is reached or (b) a host check results in an
OK state. "
 
The documentation states that Nagios dedicates all resources to checking
this host and then sends a notification that the host is down.  The part
that seems a little strange to me is that often I will get a Host Down
notification while Nagios is still doing test 1 out of 3 for the SSH
service.  I have my max_attempts set to 10 for each host, what is the
interval between these attempts?.  Is there anyway to tell Nagios to perform
host checks that are a certain interval apart (just like in service checks)
before sending a notification?  
 
 
Thanks
