Cool to see Vantage mentioned here! I work for them, mainly on the ec2instances.info site.

https://docs.vantage.sh/autopilot/ has many details on how our RI management program works. We recently added Autopilot Controls which lets you specify categories of instances (like c5) or regions that you want managed.

One note on buybacks: they are usually capped. I believe most providers cap their "guarantee" around $20K.

I didn't know this page existed, but nice work. I like how you display this data and make is so easy to do comparisons. This is a great resource.
