Rewards are cumulated till they are paid. Payouts only on poolers voting on all fellows (with green flag below). A refund 1 lsk is automatically given to poolers completing all votes on fellows, this refund is logged and can occur only once (and only on account with more than 400 lsk). Regularly, rewards not claimed may be partially given to Sherwood fund 204440690178793746L, or distributed to "green" poolers.
