[nsp] Normal time for Active->Standby Switchover (6500 Sup1A)

[Brian]

Can anyone comment on what the normal time would be for a 
Active->Standby Sup1A
switchover on a 6500?  I was looking on Cisco's site, and saw that they 
  did say for RPR it was
like 2-4 minutes and for RPR+ 30-60 seconds.  But it looked like RPR 
was a IOS feature,
and I am running Hybrid (6.4.3).  I realize that after the Sup 
switches, spanning tree has to
reconverge.  High Availability is enabled.
