If you start with cross, then technically it takes zero moves.

1 move for the cross. Most crosses are about 6 - 8 moves. One move is a 90 degree or 180 degree rotation, by definition. If you practice the time should be about 3 seconds to make the cross. I can solve the whole cube in 30 seconds, and my average amount of moves for the whole cube (in case you want to know) is about 50 - 60.

I've managed to do it in 5 moves, if you count $$m$$ moves as one move.

i think that you mean minimum number of moves in any permutation required to form a cross shown above .. if one move is 90 i think it is going to be 5 or 6 . a good problem let's try to find out what should be no of moves . as we can see the other colours do not matter it is going to be less tedious .
