Just curious:
How long (expected/ actual; average/ range; minutes/ hours/ days/ weeks; buy/ sell/ spread; etc.) is your holding time of individual options-trade?
Have you ever changed your holding time significantly? What were the major impacts?

Practically it depends on individual's trading timeframe, style (directional, swing, etc.), strategy, etc.
Is trading Gambling or not? It all depends on the number of PhDs!

"The first risk measurement that concerns the option strategist is how much current exposure his option position has as the undrlying security moves. This is called "delta".

"plethora"?
imo, to be fair, Greeks/Deltas have their values in analysing, evaluating/presenting and structuring/formulating the dynamics of complex strategies, if we really want to.
A simplified pricing model according to Gallacher (who uses basically no conventional Greeks including Deltas designed for measuring various sensitivties related to OpPrices):
OpPriceATM@t=StrikexIVxSqrt(T_Exp/254)x0.4
imo:
Profit/Loss_t1/t2=f(IV;etc.)@t2-f(IV;etc.)@t1
IV=f(OpPrices;Rate;etc.)
OpPrice=f(ProjULPrices;Strike;T_Exp;etc.)
ProjULPrice=f(HistULPrices;etc.) for some technical traders
Depending on what trading model to use, the value of HistV may generally have little direct impact...
