Units: The Universal Measure of Betting Performance

## Why Units, Not Currency Bettors who track performance in pounds, dollars, or euros face a problem: stake sizes change, bankrolls grow or shrink, and currency amounts are not comparable across different operation sizes. Units solve this. One unit = one standard stake. Regardless of whether that unit is £10 or £1,000, performance measured in units is universal. ## The Unit Definition At the start of any tracking period, define: 1 unit = your intended standard stake. This does not change during the period. If you increase your stakes mid-period, start a new period with a new unit definition. ## Expressing Results in Units - Win 3 bets at 2.50 for 1 unit each: 3 × 1.5 = +4.5 units profit - Lose 2 bets for 1 unit each: −2 units - Net: +2.5 units If your unit is £20: net profit £50. If your unit is £100: same 2.5u result = £250 profit. The performance is identical in units. Units allow bettors of all sizes to compare results and evaluate the same system. ## Variable Stake Sizes Not all bets are equal. You may bet 0.5 units on uncertain selections and 1.5 units on high-confidence picks. Express each bet as a unit multiple. Total return = Σ (unit size of each bet × decimal result of that bet) − Σ (unit size of each bet) ## Units and ROI ROI (Return on Investment) = (Total profit in units / Total staked in units) × 100 A bettor who stakes 100 units total and profits 5.5 units has 5.5% ROI — regardless of their unit currency value. ## Tracking Your Unit P&L Maintain a running P&L in units. After every 50 bets, plot the cumulative unit profit chart. This is the clearest single visualisation of whether your system is producing value or consuming it.
