Constant fil_actors_shared::v14::builtin::network::EXPECTED_LEADERS_PER_EPOCH

pub const EXPECTED_LEADERS_PER_EPOCH: u64 = 5;

This is a protocol constant from Filecoin and depends on expected consensus. Here it is used to determine expected rewards, fault penalties, etc. This will need to be changed if expected consensus ever changes (and, likely, so will pledge, etc.).
