Hello,
I'm writting my own implementation of the remote cache server. (https://github.com/ThibautMarechal/turborepo-remote-cache)
I wanted to fully integrate with everything that turborepo can offer 😄
But I'm wondering how do you calculate the time saved by using the events endpoint ? (like this: https://vercel.com/docs/concepts/limits/usage#time-saved)

For the moment I just sum all the duration from all HIT events, but it does't take into account tasks launched in parrallel.
It feels weird to show that I saved 5 minutes for a build that usually take 30 seconds (because it execute 10 tasks in parrallel).
Dividing everything by 10 is not a good solution because there is not always 10 tasks, and also the user may also use the --concurrency option.
Does the calculation on vercel side suffer from the same "miss calculation" ?
