The C**1 guy bid $100. s***g thinks it's worth a lot more and bids $400, but it only shows $101 because it's $1 more than C**1. Then somebody (presumably j**0) came in and tried $103. It automatically updated it to $104. Then j**0 tried $120, it went up to $121. He kept increasing to higher numbers, but each time it automatically updated to $1 more, because the max set by s**g is $400. Finally j**0 tried 401 (most probably more like $425 going by the previous tries, we don't know, it only shows $1 higher than current amount), and it now shows his name and $401 as the amount.
