In this case I don't want to tell org-mode how many rows to calculate, and I put a table together with an averages line in its own footer section. I prefer when doing these things to output final averages and totals just under table headers then go down into detail records after that. Could someone take a look at the following table and tell me how to get an average on column 2 of this table? Cut here.
