I would put your prediction as about right.
I would say above 3rd optimistic, below 6th pessimistic. There are a few clubs with decent players, but not much backup when players are injured. Yeovil are one of these clubs. There are even more clubs without what we would call decent players, but they have more cover. We have some decent players, but we also have cover. A lot of this season will be down to who has injuries to their players and who plays who when. We are playing Yeovil when they are at their strongest. They will not be a walkover.
