At 6 gold over the minimum I have never, not once ever lost a bid against an AI opponent. Not in Dom2, and not in Dom3 (not sure about DomPPP since I only played the demo). Keep in mind that this is on normal difficulty and it may be a different story all together on higher difficulty where the AI gets gold boosts. The only time I have ever lost mercs was when I forget to bid. (Doh!)
