Started Sorrel seeds, did I over do it?

A friend asked me start some plants. I started seeds in paper pots about 2" in diameter, I planted probably 50 seeds in each pot, I didn't count, just sprinkled them. It appears to be near 100% germination. Can these paper pots be planted directly in the ground as dense as they are, or should I tell him to divide and quarter each paper pot? Or, is that even too dense?
