Divergence between mined and received NKN

There is a divergence of 50 NKN between the mined and received on my NKNX panel.

Example:

I will mine 1550, however, only 1500 have been credited to my wallet. I deployed it myself, I didn’t use fastdeploy nknx.

Would it be possible that some nodes might have configured different beneficiary address? But if there is data difference inside nknx.org dashboard, then @ChrisT knows better.

There is a very important detail that I did not mention.

The divergence is dynamic, that is, sometimes the divergence oscillates between 40 to 100

Example:
Mined: 1500
Wallet: 1460

But other times:
Mined: 1600
Wallet: 1500
