Each row is measured at that year's final scheduled purchase. The current year shows the latest purchase so far.
How this is calculated: purchases are simulated on UTC calendar days. Prices come from Kraken weekly candles filled in to daily values, with real daily market data covering 2010–2015. Amounts are in USD, and no exchange fees are applied. ROI is the gain as a percentage of what you put in. XIRR is the annualized return, meaning the yearly rate of growth, adjusted for money going in a bit at a time. Max drawdown is the deepest fall the stack ever took from its own peak. The full methodology covers the rest.
