Im at the point where i average about 45 seconds and I use 2 look oll and 2 look pll. The part that slows me down is my F2L this is mainly because I havnt learnt intuitive F2L and when I do the F2L I turn the cube alot and i would like t know how can I avoid cube rotations or minimise them?

Two helpful algs:

R2' F R F' R and R l U' R' U l'. inverse them to set them up to the cases, and learn how to apply them in your solves.
 
What is the difference between mean and average?

mean: add up all the times, then divide by the number of times.
average: best and worst times are removed, the remainder are added together divided by the number of times, excluding the best and worst of course.
 
This means there's no actual mathemathical difference? Because when i do sessions my mean and average differs.
 
Are 42mm stickerless Zhanchis supposed to be made of the same (pure abs?) plastic as normal size stickerless puzzles? Just got a mini and it feels a lot more like my solid colored Zhanchi than my stickerless.

And then you get the controversy about whether stickerless Zhanchi's actually are different plastic in the first place...
Just let it be, shouldn't be too important
