Above any more stretch of time, You can find hardly a statistically substantial autocorrelation in high frequency returns. If there was, then the above might be applicable which might dampen the influence.

People two PnLs tend not to coincide. Which 1 do you believe makes additional sense? And it is there a method to connect The 2?
$begingroup$ When you perfectly hedge (infinitesimal moves), theta will offset gamma but if you are doing periodic hedges for finite moves, you would've gamma slippage then you end up in a distribution of Pnl about zero.
Column 5: Effect of price ranges – This can be the alter in the worth of a portfolio as a consequence of adjustments in commodity or fairness/inventory costs
