It's elegant for sizing your array, but not essential. PC's nowadays have enough memory that if you make a 2D float or double array of size 1,000 rows, (when the rows of data are always less than 600 rows of data), it's no big deal.

You can afford to be Mr. Christmas with your memory, sometimes.

It really depends on how strict the requirement are, no?

But I would definitely check if there is an upper limit mentioned somewhere, because then I agree, your method is really the way to go imo.
