Hamlet Defense Level 1, but Top Provisioner?

[Mijin]

Seals are never guaranteed, but when in top 3, the odds are very high. highest at 1st, 2nd highest at 2nd, etc.

You either get a seal, or a consolation prize, i.e. a beastcoin.

It is also possible to get gather/craft accessory, but the % chance seems to be the same whether 1st provisioner or 20th provisioner. Extremely low.

From first hand experience I'm pretty certain seals have a 100% drop rate for the top provisioner. If not 100, then it must be like 99%. However, I can only confirm this for rank 2 supply rating. My question was actually if this is also true for rank 1 supply rating.
