Regard to discussion in #482 I wrote my understanding how streamStats work down to the code.
Output of this tool looks like:

sessionId=508185878 streamId=10 channel=aeron:udp?endpoint=localhost:40123 : 
┌─for publisher 5 the last known position is 60069504 (~8416768 bytes before a back-pressure)
└─sender 5 is up to position 60097856 (103872 bytes the sender may send up to ASAP.)
┌─receiver 7 is up to position 60097664
└─subscriber 2 has 0 bytes in backlog

└─sender 4 is up to position 60097856 (101888 bytes the sender may send up to ASAP.)
┌─receiver 6 is up to position 60097664
