At iGi, we have the same metrics about training so in my Business Manager role, I have a metric called “Number of participants”, with a link to a google spreadsheet with each event and the number of participants per event.
Same for the profit per event.
Thus, we have a document I can use in my day-to-day work and there is a clear table for each event. For the profit, it is very convenient as I directly have the total.
Does that answer your question? I'm not sure...
