Yes, I am the owner. Script is set to pay each round only a little more then min transaction value is (set by devs, you can check it on github). that check is run every 5 minutes. If there are coins in wallet (matured) it will pay everyone it can.

those predictions are just sum of submitted shares which was not yet paid. Which means, they were not marked as vtcpaid or monpaid in database.

I am trying to get to show coin balances on node wallets in some inteligent way. Not sure when I get it done.

you can always check our vtc mining wallet http://explorer.vertcoin.org/address/VkJkGBLemPnnTML9MB5P557ZLZw5znqABt right now it has a balanace of littlebit over 20 VTC which are all immatured (~5h mature time).
