The Probability of You Existing

The probability of you existing is going to be proportional to the number of observers, right? Beause if we rule out these eternal, infinitely fluctuating universes, then the more observers we have in a universe that is doing all sorts of things, the more likely it is to land on exactly an observer like you. So roughly, this will sort of saturate, right? If you get to enough observers that there's probably more than one observer like you, than ou stop giving an extra bonus to large universes. The usual anthropic reasoning goes through as long as you don't use the fact you already know the cosmogical constant.
