Exit queue length

A more in depth discussion of how Rated computes the overall exit queue length

The exit queue length aims to answer this question: "If an entity or operator were to exit their validator right now, when will it actually exit the Beacon Chain?"

To answer this question, we need to first count the validators that are currently in the exit queue (exit_epoch > latest_epoch). We divide this by the current churn limit per epoch to get the number of epochs it will take to clear this queue. We then take the minute equivalent of this number of epochs (6.4 minutes per epoch). There is also a minimum 4 epoch wait to fully exit a validator (MAX_SEED_LOOKAHEAD) so this needs to be taken into account as well.

The MAX_SEED_LOOKAHEAD is the minimum delay on validator activations and exits; it basically means that validators strategically activating and exiting can only affect the seed 4 epochs into the future. See here for more information.
