There really is no "typical acceptable" number.  Some applications break with less than 0.5% retransmission rate, and others do fine with up to 3% packet loss (meaning packets will be retransmitted.)  It also depends on whether your users are complaining or not.

Ideally, there should be no retransmissions in a private network.  But of course, in the real world, you will see some retransmissions due to smaller WAN pipes, queue starvation, etc.

What is it that you are troubleshooting?
