Event Registration Forecast

You forecast how many people will register for a technical event, and how many will attend, from the registrations already in. The forecast exists for the dates where money locks: a catering guarantee, a hotel-block cutoff, a venue cancellation-fee step. Doors day is too late to be useful.
