- [PSuU PoC Experiment](https://github.com/BlockScience/streamr-agreements/blob/6e6654d85f82cda99c6706ce013abcab1d4b719b/Parameter%20Selection.ipynb)
    - This PoC has a single goal called "System SLA", which is measured through fixed thresholds on the `Avg Downtime` (less than 12%) and `Return on Stake` (more than 300%) KPIs
    - Parameters were cartesian swept at `min_brokers` (bet. 1 and 3), `max_brokers` (bet. 4 and 8) and `Allocation` (bet. 15 and 35) 
    - N_mc = 0
    - Conclusions:
        - KPIs
            - Generally, the return on stake is around 0% and 1000%, with outliers to up to 2000% (mode:  ~300%)
            - The avg downtime is between 5% and 14%
            - The Return on Stake seems to have a linear relationship with the allocation_per_epoch, with negative intercept
            - Average Downtime % tends to increase linearly with `min_brokers`
        - System SLA
            - `allocation_per_epoch` carries about 60% of the weight for deciding if a scenario is going to achieve the SLA
            - `min_brokers` is the least important, with ~10% of the weight

- Scoped experiment for having a minimal demonstration of the PSuU methodology on the Streamr Agreements Model.
    - Will involve implementation of a basic PSuU workflow
