$begingroup$ If you evaluate just only one illustration, it may seem to be the frequency of hedging directly consequences the EV/Avg(Pnl), like in the problem you described where hedging every moment proved for being more profitable.

$begingroup$ @nbbo2 I am working with the precise rate route in the instance for just a rationale, it disproves the basis of delta-hedging frequency not directly influencing PnL. And that i signify "envisioned P&L" as the choice premium (PnL) replicated by delta-hedging a place which may be calculated by subtracting understood volatility from implied volatility.

Should you hedge each individual minute, You would not understand the total pnl on the much larger SD moves but you do capture the full pnl of the more compact intraday moves.

Due to your very last equality I know that the "college situation" pnl will take into account the overall performance of your money expenditure with the gain built together just how, that may be $PnL_1rdelta t$.
$begingroup$ In case you completely hedge (infinitesimal moves), theta will offset gamma but when you do periodic hedges for finite moves, you would've gamma slippage then you end up in the distribution of Pnl about zero.
$begingroup$ Really By natural means the two PnLs do not automatically coincide. During the "college case" you don't touch the portfolio at $t_1=t+delta t$ and liquidate it only at $t_2=t+2delta t,.
