If you mean just the basic method...then:
T perm + setup/down moves = 4 seconds
J perm + setup/down moves = 4 seconds (these are averages)
Y perm + setup/down moves = 4 seconds
on average you have to solve...11 edges, 7 corners???
44 + 28...
It is hard to distinguish the lucky case, but on a really easy solve, if you go by the rules on speedcubing.com...
you get 8 edges + 6 corners...= 32 + 24 = 56 seconds, of course those executions aren't amazingly fast, but I think that if you did, with no delays at all...then you could get a 40 seconds execution and with good memo a 30 second memo...its possible...
Meh...this what ur looking for???
