Task 7: arbitrary error margin?

[miri64]

Why does Task 7 ask for a success rate of <10% for UDP packets but a success rate of <20% for ICMPv6 packets? What -- in the author's mind -- made UDP (uses 8 byte header, has checksum, might be header compressed) more successful at delivering packets than ICMPv6 (uses 8 byte header, has checksum, is not header compressed). Just the fact that one is compressed and the other not?

That's simple: Ping requires a Pong, the UDP is measured only one-way. But we should definitely change the wording, because every test says XX packets lost on the pinging node.
