I try to explain it "better".

I'm in a bid, I make one offer when the countdown is finishing (one second at the end). In this way the countdown will restart to 60/30/20 secs (it depends from the bid tournament).
My competitor manager make his offer at the end of the countdown (one second to the end), but the countdown it will not restart and the bid is closed. My competitor manager win.

Today I have lost several bid (and token) in this way. Really.
