Mark and recapture, population estimates--very common in wildlife studies

This is how the brain of my husband works....I'm telling him that I'd like to figure out how many other extras are applying for the same job notices I'm applying to--essentially what is my competition. Now that I've done 16 shoots, I am definitely seeing several of the same people over and over again at these various shoots.  It's nice because it increases the camaraderie and sense of community.  Easy to share experiences, tips, inside jokes, etc.

I'd say that on any given shoot, I recognize now about 10 percent of the people from other jobs.  Bob says he can calculate an estimate of the potential applying population if I start to give sample counts of those I recognize and how many total extras there on any particular job.  It's a method he learned in a class back in graduate school for Quantitative Ecology--over 25 years ago.  It's called Mark and Recapture for population estimates. I'm going to pay closer attention and start feeding Bob data so he can develop the model.  Nerd Alert!! And that refers to both of US!!
