I think in most bounties, a big allocation goes to the signature campaign, but most times if there are campaigns like content creations which involves articles and YouTube, then the bigger allocation goes to this section of campaign, so it all depends on the bounty manager, his aims and what he is working on achieving for the team. In the same way, there are bounties in which the signature campaign will be on a different thread with its own allocation, and other campaigns on another thread with their own allocation still about the same project and when you check most times, it can be seen that the allocation of the signature campaign is bigger. Lastly, I think the team have an influence on the campaign, because it seems there is a particular section or campaign they want to leverage on to draw more attention to their projects, hence the reason in most bounties, it is only signature campaign.
