IP SLA Default Route state down to much

Question

Hello,
I am attempting to use IP SLA trackers to dynamically set the default route going out over a DSL connection.  if the sla trackers are down the default route learned from the WAN will take over, but normally we want to send internet/default route bound traffic out over the DSL connection.  
ip route 208.67.220.220 255.255.255.255 1.2.3.4
ip route 208.67.222.222 255.255.255.255 1.2.3.4
ip route 0.0.0.0 0.0.0.0 1.2.3.4 track 3
track 1 ip sla 1
 delay down 60 up 60
track 2 ip sla 2
 delay down 60 up 60
track 3 list boolean or
 object 1
 object 2
ip sla 1
 icmp-echo 208.67.222.222 source-ip 1.2.3.5
 threshold 1000
 frequency 10
ip sla schedule 1 life forever start-time now
ip sla 2
 icmp-echo 208.67.220.220 source-ip 1.2.3.5
 threshold 1000
 frequency 10
ip sla schedule 2 life forever start-time now
the issue we are having is if the SLA threshold is breached, it immediately sends the trackers into a delay down state.  the tracker delays down for 60 seconds, then very quickly comes back up.  What we want to accomplish is only if the sla tracker has breached the threshold or is down for 60 seconds, then put the tracker into a down state.
Thanks.

The configuration seems to be correct: IP SLA change as soon as the icmp fail but the tracker delay should ensure the it changes its state after 60seconds of icmp failure. Do you experience a different behaviour ?
What I'm worried about is that, after the default router through the WAN is in routing table,  the ip sla ping will be successful and therefore the static route 
ip route 0.0.0.0 0.0.0.0 71.32.39.46 track 3
will be used but, at that point, which is the path to 71.32.39.46 ? 
Another thing is that, in case of DSL link failure, this configuration will not automatically revert to WAN link because 71.32.39.46 will be still up and running, isn't it ?
Let me know,
