let's see, I've got 8 3x3x3s, let's just say 30 seconds each with a pause of 5 seconds total
4.05
I've also got a 2x2x2, 15 seconds added, and let's take a second to grab the next cube
4.21
then my 4x4x4s (I've got 4), My eastsheen takes me about 2.40, mefferts (2) are 2.25 and my rubik's, well, just forget about that one.
7.26
okay, 5x5x5, I have one which works (other one's broken), 3.30 minutes
10.56
and then the annoying stuff begins
6x6x6: about 8 minutes
18.56
and 7x7x7, 15 minutes
33.56
add some magics, 2 seconds each. I've restringed 3 yesterday, so that'll be 6
34.02
pyraminx, about 25 seconds
34.27
wait, I've got another one
34.52
megaminx, haven't done that one in a while, I'll just give it 4 minutes
38.52
clock, 15 seconds
39.07
and that's about it
