Thank you for doing this experiment!

It's great to have this data.
Minor question: I assume CECPQ1 stands for something like Concatenated Elliptic Curve w/ Post-Quantum #1, right?
Bigger question: will there be a CECPQ2 experiment? I really hope so! Based on how CECPQ1 was constructed (X25519+Newhope), and how this experiment was executed, I'd love to see Google continue playing an active role in PQ experimentation.
