Why do some TCP congestion algorithms stay in a congestion avoidance state all the time ?

How did you get the values?

That is the really bad thing about congestion avoidance algorithms like RENO. Once a session has entered congestion avoidance mode it will never escape.

Don't know, have no good test setup for reproducing it. But I would give CTCP from Microsoft give a try. Because as I understand it right it doesn't grow linear after the congestion. I am curious about your findings.

I think the only one is probably BBR, which is pretty new:
