We are just saying that calling a downswing variance is a bad idea without a lot of time spends reviewing your play, and even then you can still be wrong.
As far as 20k hands... you need 10k hands to even get a idea if your a profitable player... 100k hands to know anything like what your true winrate is.
If you have less than 20k hands, you dont have enough information to call it a downswing(90%+ of the time anyway)...
Not because you cant have a downswing for your first 10k hands, but because you simply dont have a long enough history to know much of anything (about your true skill) yet.
I disagree with this. I need 100k hands to know if Im currently running at lower than my projected [atleast semi-accurate] winrate, I dont need a set amount of hands to say that Im in a downswing in general. If after 10k hands I lost significantly more hands than I mathematically should have, is that not a downswing? If I lost with Aces to Kings all in preflop a disproportionate number of times, isnt that a downswin, isnt that variance? I never said my play was perfect or that I know my true winrate, I simply said that the vast majority of the losses over that 10k sample were due to the downside of variance, not bad play, I dont need a certain number of hands to say that. I do not need a determination of my "true skill" to know the true odds, and to know when, over a certain sample of hands [which in this case is referred to as my downswing], those odds arent falling correctly.

Ehm, a downswing doesn't mean you're playing bad. It's a possibility. The ones that come to mind are:
- psychological factors interfering with your play (stress or distractions or whatever) without you being aware of it.
- your game has been sucking.
- you have adjustment problems, possibly because you moved to a new site or new stake - the interface, the betting amounts and the playstyle might throw you off balance.
- the cards are simply being bad for you (this is true variance).
- you get tilted easily, so a downswing will enhance itself.
So, it really can be just cards, but before you jump to that conclusion, I'd look at some other factors too. Variance does happen, but if it becomes a scapegoat to not work on your game, it's bad.
I agree with all of this, what I disagree with is when people assume that a downswing is due more to bad play than to variance. Often times yes what people perceive as variance is really bad play, but that isnt always the case.
