No idea but I'd love to know because I have 2 in the works accounts with spreadsheets with some hilarious margins where the data COULD be perfect but I don't know. Drives me nuts. Anyways. I don't recommend it unless you like hating yourself. As far as floors- depending on the formula I was "below" it till about 23, but some formulas are job specific. I sort of outgrew it pretty fast though.
