Thanks guys for the feedback and bug reports.
I updated the site and fixed the scramble issues (bigger cubes, pyraminx, 26 moves).
I also added a very basic view of everyone's averages + single solves, but didn't link to it yet, because it's too ugly

.
Regarding to
- POP: For me there doesn't exist a POP. You start your timer, try to solve the puzzle and stop the timer. If the puzzle isn't solved when the timer is stopped, it's uhm not solved. If you really want to use POP, you can make a notice in the textbox. (I know, you can't read your comments anywhere, but that's on our todo list)
- Average of 12: The thing is: At the moment i can't offer two types of averages without rewritting many things. I could change the attempts count to 12 for every puzzle, but thats not very beginner friendly. Mhh, i hope the solution will pop in my mind during the next few hours.
- Best single on the user page: Todo list...
- "X" and new scramble: Actually the "X" is just for accidentally pressing the space button or stuff like that.
@LarsN: I'll have a look at the timer at such a low resolution tomorrow, but i have to get some sleep first.
@Lucas: Your 10.88s solve is recorded. The 0.26s solve was the first solve of your second average. I'll just delete the average and hope that it wasn't a timer malfunction. So if anyone notice something similar, don't hesitate to write me an e-mail

.
- You might want to hint at what "Add" does. I didn't know, so I just tried it.
- Why am I not allowed to do more than five solves?
- Is this intended to replace the speedcubing.com UWR lists?
- I'd like to edit/delete some of my results.
- I changed the name, i hope that's enough
- Added RA to todo list
- Uhm, i never thought about that, i don't know
- I think i won't add a feature to edit your times, since it's not necessary in my opinion. The delete "feature" is already implemented, but - as i mentioned above - not yet visible.
/edit: sorry for the bad layout, i'm too lazy and tired at the moment.
