I dont have a target event date. Should i still choose a random one?

Without events (probably the situation for many of us!), is it optimal to just iterate base-build (by shifting around event dates)? Or base-build-peak? Stay in base?

Does it even make much difference for endurance class?

If I take this literally, we can all go watch Netflix. Surely some build up helps, and the question is what would be optimal.
