What is the maximum number of nodes that can be placed between two User Input T

Then what is the alternate of this if we don't have any count limit.

I assume you "don't have a limit" because a User can opt to keep looping back to the first User Input Task? You should consider a re-design if this is the case and see if you can leverage the power of a dynamic SAIL interface to conduct the processing in a single SAIL interface (if I've mis-understood or assumed incorrectly then we'll need some more details in order to be able to help you)
