How long did you take to get to sub-15 since the time you cracked sub-20?

[Dacuba]

It took me 10 months for getting a sub20 Average of 50. And another 7months to archieve a sub15 average of 50.
I think it is imortant to say how long it took you to get to sub20. OP can estimate his progression better in that case.

btw it took me another 7 months to get to sub14 average of 50 :P
Now I am in the 13s for about 4 months.

1 year since I became sub 20 and still not sub 15

[cube-o-holic]

Over 2 years and counting.

edit - roughly a year from beginning to learn F2L till sub-20.
Have had sub 15 avg of 12 but that really doesn't count as being sub 15.

[Ninja Storm]

It took me about two months, but, as Kevin said, I have stupid progression as well :P

[Renslay]

Avg12? About 4-5 years, still counting. UWR?

[FinnGamer]

I'm 90% There and it has taken me 1 1/2 month. I'm guessing I'll be sub 15 in september

[sneaklyfox]

Wouldn't it also depend on how many hours one practices each day? 2 months @ 5 hours a day or 10 months @ 1 hour a day?

[Petro Leum]

yeah its the total time yo uspend cubing. i stayed at 18/19 averages for a lognt time since i didnt practice at all. then after one month with much practice, i am now nearly sub15.

It took me about 6-7 months, with some fast improvement in the 17->15 area.
After sub-20, how you practice becomes a much bigger factor in improving than it needed to be before. Practice alone is still obviously helpful, but that alone might not get you to sub-15.

It took me almost a year, because I'm lazy and slow at learning algs.
