It depend of the estimate setting.
With "estimate client", -1 and -2 will be a failure
With "estimate client server", -1 will use the server estimate and -2 
will be a failure
The problem is if server is listed before client
   estimate server client
In that case, the application estimate command is never executed and the 
server estimate is always used
