Excel supports formulae that are difficult to read. Though we can use a VLOOKUP, we have to engage our brains to make sure we understand what it's doing. And when we see a formula that's a mile long grabbing data from multiple worksheets and workbooks, well it just make us want to take up market gardening.
Packola's reduced instruction set means you can't do those sorts of things. It's instant to see how any number's come about. The colour of the cell type tells you a lot. Precedent squares are a direct copy of a number calculated on another board. Formulae work only on the squares on the current board. And there's no VLOOKUP at all.
Reduced instruction set means reduced confusion. That leads to confidence and clarity.
