Boarding parties question

[dmm]

1. Cool idea, Zanthis.

2. Getting back to the actual game: Can multiple, level 1, boarding parties (BP1) defeat a single, level 2, defense station (DS2)? How is that calculated? Would it be like this:
1 DS1 beats 1 BP1;
1 DS2 beats 1 BP2 or 2 BP1;
1 DS3 beats 1 BP3 or 3 BP1;
and so on?

3. Somebody claimed that boarding fails sometimes and that multiple BPs increase the chance of success. I don't seem to recall a BP ever failing against a ship with no DS.
