Forum:The awakening of the Elves

In the Silmarillion, when the elves first awaken, there's obviously some time before the Valar stumble upon them in which they can possibly procreate and grow in number. After their 3 representatives visit Valinor and return to bring the elves to the West, the Silmarillion describes the three hosts and their varying sizes. Just how many elves do you think would there have to have been for large "hosts" to depart, and even for great numbers of Avari to be left behind? Did they awaken in the tens of thousands? Did hundreds of years pass before Orome found them? Just looking for thoughts!
