hobbitlaunch has a built-in safety catch, so you cannot run a
task more often than once every 5-10 seconds. That's to prevent
it from fork-bombing your system.

If you really need that, use a wrapper around your script:

   #!/bin/sh

   while 1
   do
       /usr/local/hobbit/client/ext/hiflow_net
       sleep 1
   done

and run the wrapper-script from hobbitlaunch (without any
INTERVAL setting since it keeps running).
