The sheet that uses limited ranges shows perceptably better performance

When an array formula is applied to an entire column then it evaluates very slowly. When applied to a limited range it evaluates much more quickly.

I believe this is due to the formula being applied to the full range, rather than just the limits of the sheet. I consider this a bug rather than an enhancement as I cannot see a reason for evaluating outside the limits of the sheet (as determined by pressing ctrl-End). Specifying a full column range allows the sheet to grow indefinitely while performance degrades in proportion to the size.
