Just curious: Can I "recover" the analytic description ( say, like a Mathematical expression) from a graph?

I just did well on a Sudoku recently . Please see below:

The curve looks a lot like Plank's curve for black body radiation. You could try curve fitting your results to it or do your future Sudokus under a black light. :-)

Thanks. As usual I am being a bit lazy, just wondering if someone has thought this thoroughly so I don't have to. I may have to take a radical approach and think it through. Seems like it may be in the Chi-squared family (From the tanning salon family :) )?

I think that something like the time to complete a Sudoku puzzle would follow a log-normal distribution.
