We updated our delegation script to change how payouts are calculated.
In the past we used a fixed percentage of the developer account to calculate how much APE will be distributed daily. With a recent update we are dynamically calculating how much APE will be distributed using previous days curation rewards + 10% bonus.
This change will provide a predictable return and bonus over actual curation rewards received. The 10% is calculated off the average spread price of APE on the Hive Engine market.
Based on initial tests, the return will be roughly similar to what you are seeing now but will be more predictable as delegations are added/removed.

Rewards are distributed nightly at UTC midnight as APE tokens, which can be traded, held, or used in the Ape Mining Club Game.
