My code search tx[0]vout for payee like this.
1) compare tx[0]vout  with previous recorded getblocktemplate result +3) : hit : got equlto, fail next.
2) compare tx[0]vout  with current Masternode pubkey list +3) : hit : got innmlist, fail next.
3) compare tx[0]vout[value] : >= totalvalue 10, < totalvalue 3 : hit got not_detected. next (time outed node can be a payee)
4) tx[0]vout == 1 : got tx_0_vout_1 not paid

: So innmlist means == diffrent payee with result of getblocktemplate(can be different), but payee is in Masternodelist.
