Trying to Understand CPU Time

📄Logs

Workers

I am relatively new to Cloudflare and am trying to get an understanding of worker metric breakdowns. I have these metrics over the past month:
Requests - 602
Subrequests - 16
CPU Time - 10.03ms
Wall Time - 802ms
Request Duration - 785ms

I noticed CPU Time is 10.03ms and am wondering if this is the CPU Time Per Invocation or if it is total? If this is per-invocation, will I be billed for each request?

More details for context:
The Overview metrics are showing for the last 24 hours
Requests - 208
CPU Time - 8.43ms

When on the Workers & Pages page, the Usage from December 1 - December 4 shows
CPU Time 2,043ms

And then strangely when I go into the Metrics section and choose Last 24 Hours, it shows my CPU Time to be 8.43ms and then jumps to 22.61ms

Obviously I'm well under the requests amount, but I am very confused as to how the CPU Time works and if I'm over the free tier amounts or not. Thank you anyone for the help!
