Hello!,

Yes, trusted peer and attacker have always the same position (attacker - 1,
TP - 2), but this doesn't affect on the result because of random latencies.
Splitter always have peer list in random order because of latencies.
Here's log file of experiment with 50 peers.
https://www.dropbox.com/s/cy2ljkacbs605c3/log_50peers.txt?dl=0 - 100
experiments, 50 peers, with buffers (48 Mb)
https://www.dropbox.com/s/rmiet1vby1f46hf/avg_posioned_chunks_a1_t1_p50.txt?dl=0
- 100 experiments, 50 peers, without buffers (167 Kb)
When I prepared the results, I simply 'grepped' the strings with regex and
paste it in google sheet.

Also, I have pushed the new code in my branch (lp:~im-shakirov/p2psp/sim)
