Hmm, not sure I understand this?!
To my understanding the rewards are stuck in the accounts reward balances, but not in the Steem reward pool?
The Steem reward pool is defined from all active rshares (recent_claims) in combination with the network inflation (reward_balance) and the price feed. This defines a Steem value for rshares. On payout time, the rshares values are credited to the account reward balance as STEEM, SP and SBD using this value. To my understanding this is not part of the Steem reward pool then anymore. After claiming resources, the account reward balance is transferred into the account STEEM/SBD/Vests balance. The quotient of total_vesting_shares and total_vesting_fund_steem should not change between before and after claiming rewards. Am I missing something?

As far as I understand, if rewards are not claimed, they remain in the rewards pool. Otherwise I couldn’t explain its irregular variability. So, as long as you don’t cash out what’s in your rewards balance, this should count towards the rewards pool as well.

But I might be wrong.
