I was mining PPTP with http://pptp.ukkey3.space/ for a while but discontinued as the site announced its closing down.   When I tried solo mining instead, I got 45 PPTP coins for block reward that is 9 coins more than what the pool was distributing.   I made an inquiry to the pool why only 36 PPTPs are distributed instead of 45 and got answer that 9 coins are for masternode reward.   

People have mined  around 7000 PPTP blocks with the pool so far.  The 9 PPTP coins per block, amounting over 60K PPTP coins were really distributed to the masternodes?  Why I am getting 45 PPTPs with solo-mining?  Is there any trick about it?  Can anyone tell?

Although the coin has no value at all,  I just wanted to clarify that out of my curiosity.
