A sample of 121 [integers](https://artofproblemsolving.com/wiki/index.php/Integer) is given, each between 1 and 1000 inclusive, with repetitions allowed. The sample has a unique [mode](https://artofproblemsolving.com/wiki/index.php/Mode) (most frequent value). Let $D$ be the difference between the mode and the [arithmetic mean](https://artofproblemsolving.com/wiki/index.php/Arithmetic_mean) of the sample. What is the largest possible value of $\lfloor D\rfloor$? (For real $x$, $\lfloor x\rfloor$ is the [greatest integer](https://artofproblemsolving.com/wiki/index.php/Floor_function) less than or equal to $x$.)
