nice summary, boy you got that together fast. but to make it just a bit clearer, I'd include their example:

The tokens for a window will be split proportional to all contributions made during the window period.

For example, if 20 EOS are available during the window:

• Bob contributes 4 ETH
  • Bob contributed 80% of the total contributions and gets 16 EOS
• Alice contributes 1 ETH
  • Alice contributed 20% of the total contributions and gets 4 EOS
