Said stab is starting to look pretty usable.

I’ve created a new repo [GitHub - sourcecred/payouts: Tooling to generate payout data from SourceCred.](https://github.com/sourcecred/payouts)

Which is published to NPM as [@sourcecred/payouts - npm](https://www.npmjs.com/package/@sourcecred/payouts)

And I’ve refactored the week2 payouts notebook to use it:

There are some discrepancies between it and [the original](https://observablehq.com/@decentralion/sourcecred-credsperiment-week-2):

- In the **Fast Payouts** table, the “% cred” column was incorrect in the original.  
`{name: "% cred", fn: (a) => fastPayout.get(a) / totalFastPayout, format: percentFormat}`  
This `fastPayout` and `totalFastPayout` represent mana, not cred.
- In the **Slow Payouts** table, the “Target total payout” column had a rounding issue.  
The original used `Math.round()` when _displaying_ and used the sum of _unrounded values_ for the total. The new version uses `Math.floor()` for each user, and uses the sum of _rounded values_ for the total.

Also, a request to include this repository in our instance.

Thanks @Beanow! I’ll use it for the next canonical grain distribution.
