I must almost certainly point out that I didn't say which method is right. Just wished to give the reason why They're various.

$begingroup$ If you take a look at just an individual example, it could look like the frequency of hedging directly outcomes the EV/Avg(Pnl), like in the situation you described where by hedging just about every minute proved being far more profitable.

Plus the incremental PnL of a long approach in between $t$ and $t+delta t$ is calculated given that the earnings produced by borrowing The cash to buy the risky assets at $t$, then providing out your posture at $t+delta t$. So in my example:

The purchase isn't going to matter for unbiased brute-force P&L or for threat-theoretical P&L (Taylor sereis approximation in the P&L making use of deltas - initial get and gammas and more info cross-gammas - next purchase threat steps).
