Which is dependent upon the rebalancing frequency. But "predicted P&L" refers to a mean over all possible cost paths. So There's not always a contradiction right here. $endgroup$

$begingroup$ For those who completely hedge (infinitesimal moves), theta will offset gamma but when you need to do periodic hedges for finite moves, you might have gamma slippage then you find yourself inside of a distribution of Pnl all-around zero.
In several situations (like bonds inside your scenario) these costs are noticed and unambiguous, This can be 'marking to market'; in other scenarios (where you may keep an illiquid exotic, similar to a PRDC for instance) this rate is estimated because of the Front Business office pricer, this is 'marking to product'.
Vega p/l is by definition the p/l as a consequence of moves in implied volatility. The 2nd Element of the dilemma you have got answered on your own. Limited dated possibilities have a lot more gamma exposure, extensive dated selections have far more vega exposure.
Vega and Theta are sensetivities to volatility and time, respectively, so their contribution would be:
Over any longer time frame, There exists rarely a statistically significant autocorrelation in higher frequency returns. If there was, then the above can be applicable which might dampen the influence.

$begingroup$ The knowledge I have found about delta hedging frequency and (gamma) PnL on This website and numerous others all reiterate the same detail: which the frequency at which you delta-hedge only has an effect on the smoothness and variance of one's PnL.
