I have been shocked today when I saw that I earn from second to eighth level in upgrade commissions ONLY!!!
I though that I earn also from referrals clicks through 8 levels, but It is wrong!
So, how did "valerie" make $205 from her second level while she has only 45 upgraded referrals?!
(she should make only $45 only from her 45 upgraded referrals!)

How did she make $904 from her third level while she has only 236 upgraded referrals?!
(she should make only $236 from her 236 upgraded referrals!)

She is a God!

You forget, I've been here 5 years. Some members come and go.

Some may have upgraded one year and not the next. Some may have stopped working online.

The above image is an image of my present active referrals and the total amount I have earned over time.

For example, tomorrow I might have 409 active on my second level but my total earnings for that level, remain the same...unless someone else upgrades.

On levels 2 through 8 you earn only upgrade commissions. And that is what valerie has earned. No click commissions there.

There is no reason to be shocked. Everything is explained on this page: ClixSense Affiliate Program - Refer Others And Multiply Your Earnings!

I have a question, do I get upgrade commission again if my downline renew his premium subscription after a year?

Follow up question, what if he will renew 2 year upgrade, how much will be the commission?

If we will be paid again then that explains why valerie has $205 even though she has 45 level 2..

Yes you get paid again the next year when that member upgrades again.
Every time a member upgrades, you earn the upgrade commission.
If a member pays for two upgrades, you get the commissions twice.

And yes, that is another reason why there could be more commissions showing for less referrals.
Some may drop out and no longer display as active or become inactive but also as you said, some
upgrade every year....it is yearly residuals on each member that upgrades again, year after year.

Let me clarifiy about the 2-year upgrade. You will get paid the same amount as if it was a 1-year upgrade. In other words you get it only 1 time within the 2 year period, as opposed to being paid twice if you referrals chose to upgrade yearly in the 2 year period.
