Random Cubing Discussion

Well, I was solving my 2×2 the other day and it popped. Which has only happened 2 times before, I was having a hard time getting the piece back in and then I realized it had actually broke. So now I no longer have a 2x2 -_-
 
I'm averaging a bit over 20 seconds and my last layer is about 5-10 seconds (my first two layers takes about 9-13 seconds). I notice I'm really slow with algs, for example my J Perm time attack best is only 1.46 and I normally, in execution on a random alg, take about 2-4 seconds. Is that normal?

I also sometimes get stuck in the middle of algorithms, as in catching, but I think that's something to do with tensioning or maybe lubing.

I broke my DaYan 2x2 centre piece... the cube still worked fine though; the only difference was that it popped more often.
But someone wanted to buy it, and now I now don't have a DaYan 2x2 :(
 
Take a 6x6 and do the following:
Turn U by 15 degrees
Turn 2U by 15 degrees
Turn 3U by 15 degrees
Turn 4U by 15 degrees
Turn 5U by 15 degrees

You'll now have this cool fancy spiral looking cube. Let's say I was solving and stopped the timer with the cube looking like this. Would it be considered solved or +2?

I say it is a +2 b'coz the U layer will also move when move the other 'U' layers
When you turn 3U by 15 degrees, The U layer would have moved by 45 degrees
But I might be wrong as well .
--Please correct me if im wrong

I don't know, I thought it was that each layer had to be <45 degrees from the layers adjacent to it, so it wouldn't be +2, but I'm not sure about this.
 
If given a picture of all 6 sides of a scrambled cube, how hard would it be to manually figure out what the inverse scramble looks like? I know that:
1)number of edges that are misoriented are the same
2)pieces/blocks that are solved will show up on the inverse as solved, but their positions may change

As with all problems regarding the formation of inverses (with limited information i.e. cubie colours only, no scramble etc.), the most practical way currently would be to reverse a BLD solution. If you memorised ABCDEFGH for the original scramble, Just colour the cube according to how a scramble with HGFEDCBA as the solution would look like.
