Hi,

>4. Don't turn left .. you can accomplish the same thing with 4 right hand turns and it'd be safer to.

I think that should be 3 right hand turns.
But are all the turns 90 degree ones?
If not you would need to accumulate degrees of rotation on each right turn until a cumulative total of 270 degrees was achieved.
Of course that assumes that the initial required left turn was 90 degrees.
If not then the required total right rotation would the the required left rotation minus............
