Entry Points don't appear in the Unity Profiler.
When using the unity profiler you wont see a breakdown of your entry points using ITickable etc. Just the player loop dispatcher Invoke call.
Makes using entry points very risky.
Solved by using Deep Profiler.
@SimonNordon4 Is EntryPoint less visible in the profiler than MonoBehaviour.Update?
I think it should be at least as profiled as MonoBehaviour.

Normal Profiler is only showing me UpdateFunction, there's some complicated boids behaviour occuring within that.

Monobehaviour is showing more details.

With deep profile on. It might be expected behavior I'm not sure. I guess the benefit is being able to see which EntryPoints are using resources. Although I'm going to stop using entry points for 'monobehaviour' logic.
