I've kept meaning to generate these, and I've finally got round to it -- see 

My lists agree with Phil's lists of 2, 3 and 4 bobs, and I've also included 
lists for 5 and 6 bobs.  (Unfortunately there are so many possibilities to 
examine with 7 bobs that the server running the CGI script gives up after a 
few thousand successful comps, so I can't go any higher.)

For those who can't be bothered to look:
2 calls - 2 comps (0 ending in rounds)
3 calls - 19 comps (14 ending in rounds)
4 calls - 66 comps (14 ending in rounds)
5 calls - 216 comps (7 ending in rounds)
6 calls - 2146 comps (532 ending in rounds)
