You can also analyse the skewness and kurtosis with the time period PnL by taking third and 4th times of $Y_t$ respectively. Presumably you'll conclude that for 2 series with equivalent expectation and variance, you may want the a person with optimistic skew or lower kurtosis, but probably not with regards to the self confidence of the marketplace view, and so forth..
The net outcome of all that is enhanced delta hedging frequency does just provide the smoothing impact on P/L around very long more than enough time horizons.
