I would imagine that this +170-200 wood could turn your boom better so that you could possibly end up with some +7 villagers (or more?) by 27 minutes due to your boom being progressively made better.
This is how it works: Initially you could just lay down an extra farm to convert this 170 wood to 100+ food which during the early stages of boom would give you 2 more villagers (+100 food lets you make 2 more vils when you have multiple TCs). Since the 2 extra villagers are collecting extra resources this paves way to increase your villager lead even more as time progresses. Slowly it becomes +3,+4 and so on so if you ended up with +7 villagers at 27:00, finally losing a villager lead will still give you +6 villagers.
