Bug Description

The following warning is issued in the first time w/ the <strong>status</strong> option:

Use of uninitialized value in subtraction (-) at ./mysar.pl line 357 (#1)
    (W uninitialized) An undefined value was used as if it were already
    defined. It was interpreted as a "" or a 0, but maybe it was a mistake.
    To suppress this warning assign a defined value to your variables.

    To help you figure out what was undefined, perl tells you what operation
    you used the undefined value in. Note, however, that perl optimizes your
    program and the operation displayed in the warning may not necessarily
    appear literally in your program. For example, "that $foo" is
    usually optimized into "that " . $foo, and the warning will refer to
    the concatenation (.) operator, even though there is no . in your

This is due to the fact that it's trying to calculate 'deltas' when the table is empty.
