It is very difficult to say!
In fact, in many ways the role has luck.
From personal experience I am rehearsing various ends of those first wines so through junior and beyond.
Not once isam managed to win.
Last auction I tried to win me the cost 250 TC and I managed to win 4-5 and previous auction of this type have ended after very few bids.
Means you need to arm yourself with patience and TC and a lot,lot of luck!
There are no rules.
