NimbostratusLoad balancing decision

I've been doing some research about loadbalancing methods and algorithms in devcentral, and so far I haven't been able to find an answer to this question:
During the loadbalancing ...

NimbostratusI don't think so, I think it just keeps track of the amount of time since the last response. Using the time values in Vitaliy Savranskiy example it would look something like:
- Time 0 - send health check 1
- Time 0 - received response to check 1. Save last response as "0" seconds ago
- Time 1 - is last response time less than 16 seconds ago: Yes, leave as up.
- Time 5 - send health check 2
- Time 6 - is last response time less than 16 seconds ago: Yes, leave as up.
- Time 10 - send health check 3
- Time 11 - is last response time less than 16 seconds ago: Yes, leave as up.
- Time 15 - send health check 4
- Time 16 - is last response time less than 16 seconds ago: No, mark as down.
So as long as it receives a response within the last 16 seconds it will leave the node marked as being up.
