In general, the distribution of rewards to an Indexer's Delegators occurs when the Indexer closes their allocation. This process may be delayed due to factors such as gas fees and other considerations, prompting Indexers to postpone closing their allocations to minimize costs. However, it is important to note that allocations can be forcefully closed after a period of 28 days if the Indexer has not done so by that point.

Therefore, it can be expected that rewards will be distributed to Delegators no later than 28 days after the allocation was made. However, it is worth mentioning that in most cases, Delegators can anticipate receiving their rewards earlier than the aforementioned timeframe.
