Week 5 Session: Balance Sheet Clinic

Build a real cost-effectiveness ratio from provided cost and performance data, then argue for a rebalance using it — not a vibe.

22 March 2027

Before the session#

Read Week 5’s lecture on DPS-per-currency and EHP-per-currency ratios. No preparation beyond that — the data arrives in the session.

In the session#

Marcus provides cost and performance numbers for a small set of competing in-game options (which game they’re drawn from varies by year, so the data is provided fresh rather than reused). Build the ratio, write it out as a formula with the dataset’s own numbers substituted in rather than just the final value, find where it’s too flat or too peaked, and propose one specific numeric change.

• 10 minutes: introduce the dataset and the two ratios
• 30 minutes: build the ratios (as formulas, numbers substituted in) and draft a rebalance
• 10 minutes: share one proposed change with the room, stating the ratio’s value before and after it so the room can see how far the outlier moved

Afterwards#

Balance Patch Notes (due Week 6) is a fuller, individually-marked version of exactly this exercise.
