Assumptions and how this is calculated

risk_per_share = |entry − stop| + slippage_per_share
shares_by_risk = floor((account × risk% − round_trip_fees) / risk_per_share)
shares_by_cap = floor(position_cap / entry)
shares = max(0, min(shares_by_risk, shares_by_cap))
net_pnl(exit) = shares × (exit − entry) × direction − costs
R(exit) = net_pnl(exit) / |net_pnl(stop)|
