The only time it is worth trying to be the last bidder in a round is if its the last time you are going to use a token, or you are down to your last one.

I see several people put a bid in with 1 or 2 seconds to go at the end of each round, thinking they are being clever getting the bid in at the last second, yet I always bid at the start of the round. If two people are wanting that player then it will go to the next round if you bid with 20 seconds to go or just 1 second. It is that simple.

By waiting until the last possible second to bid to become the round leader you get no extra, other than you win the player if no one bids in the next round. If you are prepared to bid in the next round then get the bid in early. I know several people who use the last second bid who have lost out on players as their bid hasn't gone in on time. Its their own fault as waiting until the last possible second to bid is simply stupidity.

Of course, if you have a limit of tokens you are going to use on a player, or are down to your last token then its wise to wait until the last possible moment of a round to use the token on your LAST and final bid. Other than that its a stupid strategy.
