Level-Stakes Profit / Loss 1 unit per run at SP · 16 bets
How profit / loss is calculated

This is a level-stakes simulation: imagine backing this horse with the same 1-unit bet every time it runs, at the starting price (SP). The line is the running total — rising when it wins at a price that outweighs the losing runs, falling on a losing streak. It asks whether blindly backing the horse would have made money, a tougher test than its win count alone.

Each run settles as:
win → + (decimal odds − 1)  ·  lose → − 1.
So a win at 5/1 returns +5.0 units, a win at 2/1 returns +2.0, and every loser costs −1.0. Fractional SPs (e.g. 9/4) are converted to decimal — 9÷4 + 1 = 3.25 — before settling.

This horse's record 16 runs with a priced SP, staking 16 units in total → a loss of -9.7 units, an ROI of -60.6% (profit ÷ total staked).

Only runs with a recorded SP are counted, so this bet total can be lower than the horse's total runs. It assumes you back it at SP every single time, with no selectivity — a baseline, not a betting tip. It ignores Rule 4 deductions, dead-heats and any each-way element; a flat or rising line is the signal worth noting.
