Year 8: 8-5 = 3, so 3% of revenue (from that year or from the previous 3 or 8 years?)

3% of the last three years of revenue (first 5 years you keep everything)

Year 11: 11-5 = 6, so 6% of revenue (from that year or from the previous 3 years?)

Previous 3 years.

14 : 9% of revenue ... 103 : 100% of revenue

Check your math. :). Year 103 would be 103-5=98%

106 : 103% of revenue

Same math issue.

> If minimum revenue is $100, you wouldn't pay that much until year 103. But would it remain at $100 at year 106 onwards?

Minimum fee is $100. Every 3 years you pay at least $100 to keep the copyright.

Looks like I got the 3 and 5 years mixed up and started subtracting 3. I fixed the original post.
