Need help reconciling quantities in this recipe
That recipe, which I've made many, many times, yields approx 5-6 dozen cookies if a rounded tablespoon is used as a gauge.  For that amount of dough to only yields 2 dozen cookies, they would each be approx. the size of a golfball, maybe.  I believe your recipe has a mistake in yield.  Check out this link to a similar recipe (nestle Toll House cookies):
