Yes, youre right. I've running mine NAV masternode and waiting now for about 2000 minutes to the main block kicks in. After this 20k block the NAV rewards will generates 3.8 nlx.
This is a good project with much support on the telegram channel. I will mention to the folks to not be shy to give some feedback at this bitcoin talk forum.

And this is mine first masternode project because many others seemed me to difficult for setting up.
A little child could setup a masternode with this tutorial from NLXionaire.
If somebody is interested in setting up a NAV, here is it nice and easy explained.
