interested!

Would love to join

I could be wrong but what I inferred before hearing J.Y's explanation was that a high-selling restaurant could have been opened last year. Such a restaurant would not have had comparison data (because it's only been open for one year. ) and thus would not have been included in the figures that the accountant talks about (he uses two years of data). This question does seem more like a missing assumption though.

Interested too!
