Ok, let me get this straight:
* Price went up to $15
* I bid $51, causing the price to go up to $16
* If no one bids after that, I win and pay $16
* BUT... if the price still is $16 and someone bids $20 (not knowing I bade $51) I still win but I have to pay $21 (or whatever the first increment after $20 is), unless someone bids more than my $51.
Correct so far?
