Performance question concerning AsyncReactive Property

[BillSansky]

Hi! First of all awesome work, I am blown away by the quality of the code and documentation.

My question concerns awaiting value change of Reactive Properties, or simply triggering unity event functions.

Are the value checks or event checks made every frame? In other words, will the performance be impacted by the number of Reactive Properties I use or the number of trigger checks I make?

EDIT: I made a few performance tests and it seems that the answer is no! But I'd be curious to know why that is so!
