EDIT: Whenever I see my own solve reconstructions I cannot help but notice that my F2L doesn't look very efficient. Can somebody point out better insertions (even if that spoils the PLL skip)?

My 1000th solve on Prisma Puzzle Timer!!

So today, I was just solving 5x5, and saw through my history that I have improved from my first solve by about a minute, then wondered what my first 3x3 solve was. I have improved by 15-20 seconds. In 5 months. I just did my 1000th solve today in an Ao12 (23.06 with a 16.86 single... meh average for me but very good single) but it is so cool to see that I am actually improving and that there is hope for me to get to sub-20!! By the next 1000 solves, I will hopefully be well below sub-20. Also, I should mention that I deleted any DNF's, solves that I accidentally forgot to hit the spacebar, solves where I hit the spacebar too soon, etc. Should I keep the DNF's in my next 1000 solves? Also, could someone tell me how the standard deviation, quartiles, and median is calculated? I've always seen them, but in the 1000 solves, never known what they meant.

The median is the time that would be in the middle if you listed all the times in order. The quartiles are the times that would be 1/4 of the way through the list and 3/4 through the list.
Standard deviation is a measure of how consistent you are. If your solves are all similar times, then your standard deviation will be low, but if your times are spread out then you'll have a high standard deviation.

Thanks a lot for your help.

F2L#2 - I should pay more attention to empty slot usage
F2L#3 - That's a case I can recognize when slow solving to practice F2L but when I'm in the middle of a speed solve I rarely / never see it.
F2L#4 - Yep, another one I can see when slow solving but not in speed solves. In speed solves I tend to go back to basic F2L bad habits of "hiding the corner" when in this case it's shorter to "hide" the edge.

So much to learn... I am so slow... not only solving but also learning :(

In this case I was lucky that my bad F2L set the cube up for a PLL skip but, if it had been the other way around, with your proposed F2L and a PLL skip, it would have been probably an 11.x instead of a 12.99.

At least it's nice to realize my weak points. Lately I'm very focused on improving F2L lookahead, now I know I have to also work on rotation / regrip and move count efficiency.
