-The transition with pure time, no blocks, is known as `state_transition_to(state, slot)` in the spec.
+The transition with pure time, no blocks, is known as `process_slots(state, slot)` in the spec.
 This runs state-caching (pure slot transition) and epoch processing (every E slots).
 
-To process the data, call `state_transition_to(pre, pre.slot + N)`. And see if `pre` mutated into the equivalent of `post`.
