Final Bid Group:

Award Work L-- ====> Every trip in play, bid group can't fail above G-line.
Avoid 1
Avoid 2
Avoid 3 -----> Avoids 1-3 are locked in the lowest (L--) bucket (stuff you hate the most).
Award Work L-
Avoid 4
Avoid 5
Avoid 6 ----> Avoids 4-6 are locked the 2nd lowest (L-) bucket
Award Work L
Avoid 7
Avoid 8
Avoid 9
Avoid 10 -----> Avoids 7-10 are locked in the "L" bucket
Award Work (N) ----> Best trips that respect all Avoids are here.

When PBS runs, it starts by looking at your N bucket which has what for you is the best flying since all your Avoids are respected there. Let's say PBS finds one trip in the N bucket that would work. PBS needs more trips of course so it goes next to the L bucket where it finds one more trip. The trip in the L bucket would not respect Avoids 7-10, but it would respect Avoids 1-6. Now PBS goes to your L- bucket. Let's suppose it finds two more trips in the L- bucket that would work. With 4 trips now, PBS has enough trips to build a legal line that hits the required credit time so it builds a line. Since PBS never had to dip into the L-- bucket, Avoids 1-3 would be respected in your line construction in this case. By doing it this way, you submit a FINAL bid group that will not fail but still allows you to negotiate with the system. If you are super junior and there are just a few trips left, the system may very well find nothing for you in N, L, and L-. In that case, the entire thing will be built from L--. You can't fix being that junior, but all you can do is try.
