I launched my masternode 2 days ago. during these 2 days i had 1 (ONE) generated income of 6.5 PURE. Is this a joke or what, 65% of the block you say in OP??
1 POS block is 10 Pure, 6.5 for a random MN, 3.5 for a staking node. Each POS block is randomly rewarding one MN and one staking node

1) Point me to where it says "10" and not "100" in ANN post.
2) Currently there are 140 masternodes running. 3 min/block equals 480 blocks/day, even with 6.5/block it's 3120/140=22.2857 coins per MN per day, not 3.25. Where are they?
1) "Block reward 100 (up to block 30'000)"

So, yes, there is no mention of the 10 Pure for the POS block, but as far as I know, all POS coins work that way, with less reward for POS block (the only exeption is the 0% POS from ghostlander) So... it's working that way, even if God isn't happy with this reality. This is how it works

2) Currently... I'm a mess at maths, so I can't help here. But I own one MN and I get 6.5 three / four times a day (the 3.5 are for staking nodes, not masternodes). So, I think you might be better than I am with numbers but maybe you misconfigured something with your MN.
