I average 13 and I get occasional comp 20s. Never at home really.
What did you average when you no longer got sup 20 times?

I've never had an official sup 20 
Had a few DNFs though but none of them were gonna be anything close to 20

You average sub 20 with OH yet you've had 20+ second solves before. It was never mentioned that he was talking about 3x3

Now that I think about it 15-16ish is when 20s got rare. Now they're just more rare.

I'm at sub19 and I get sup 20s like 20-30% times of the solves. I suppose a good std. deviation for 3x3 at sub20 is something around 1 second more or less (depending on your level of course). It's higher at sup 20 and lower at sub 10.
You can just use qqtimer, get an Ao100 and look at the std. deviation. e.g. in one of my averages I got 18.60 secs from 55 solves with a std dev of 1.64. That means that around 70% of my solves are at 18.60 +/- 1.64 seconds. The remaining 30% is divided by around 14% being 2x std deviations 2.1% of solves at 3 std deviations and 0.1 solves at 4 std deviations meaning that 0.1% of my solves should either be around 12.04 seconds OR 25.16 seconds. This is according to statistics though; I've never even had a sub13 solve and I extremely rarely get a solve that is sup 22 seconds.
If I had say an average of 18.60 and a std. dev of 1.3 I would know that I'm atleast at 17.30-19.90 seconds nearly 70% of the time which I would count as sub 20. By this logic I'm not "safely" sub20 yet as I'm 16.96-20.24. Your solves get more consistent as you improve. I wouldnt worry much about the times itself, but rather about consistency. The times will lower eventually. If you're a consistent sub 20 at home you can assume that you'd be sub 20 at a comp too, which is what matters if you care about those things. Unless you're really tense at competitions. I've seen a guy that can easily do sub17 solves do a sup 40 sec solve twice at a comp.

I'm sub12 and I while I never take longer than 20 seconds on a regular solve (even if it's a really bad one), it can happen if I mess up badly (like destroying something on a LL algorithm or something). Even so, I can usually recover in time to get sub20. I'd say I get a 20 every 200~300 solves or so.

Yeah pretty much this. Or on occasion I try to intuitively do WV. It doesn't work out...
