Upon completion, there is a box that shows statistics for the completed puzzle. The statistics include:

But how are these computed?

Success Rate - Is this the number of attempts that finished divided by the number of times the puzzle was presented?

Penalty Rate - Is this, for the number of attempts that finished, how many had at least one penalty?

Median Time - Is this, for the number of attempts that finished, the average or the median (part of the website uses median and average as interchangeable terms, but they are different: the median is the point where half are below and half are above, while the average is the total time divided by the number of (attempts that finished?).

Thanks.
