Nope, it’s not ‘power creep’ — since the ‘power’ alone ‘creeps’ equally for everyone.
PS And it could creep in a very ‘deterministic’ fashion, by the way, meaning that those impactful cards or effect could be predictable and calculable, you can make a game plan that accounts for them and so on — I’m not saying in HS, but in theory.
What you’re saying suggests that the role of skill diminishes over time — nothing more, nothing less.
If it is well within the stochastic (random) error, it is practically lost.
In plain words: if a slot machine gives you $(50 +/- 30) on average (with a certain confidence level, if you will), and your skill makes a difference of +/- $1, you can consider it a pure gamble.
And why is that? Define ‘randomness’ quantitatively, by the way.
Ugh, guess you guys will never learn. 
A statistic is by definition a function of your data (sample) — you don’t measure it (that’d pertain to your actual data), you calculate it (from the data, as said).
That statement actually looks correct to me.
And why is that, again?
As said, it seems to me that if the impact of skill is ‘drowned’ in stoctastic errors, it might be difficult to prove convergence, if there is any.
PS That was not a rhetoric question, I’d actually like to know.
Lemme tell you how.
It’s one of the same miserable troll accounts on this forum, generating the same kind of repetitive junk posts with no meaningful contents but supposedly provocative and inflammatory personal attacks — again, mostly dull, unimaginative and stock ones (come to think of it, wouldn’t be surprised if somebody were testing a crude chat bot to imitate Medivh’s magic mirror from the Karazhan adventure — but it could be just some very strange and sorry person practically living on these forums, who knows), along the lines of what that rude homunculus, or whatever the card is called, would say — at seemingly random forum posters, mostly of the ‘normie’ kind, i.e. those who post something more or less meaningful.
No, I’m not an oracle, it’s these forums that are quite… predictable, repetitive even, that’s how I know it.
