Yes, certainly should be easily possible to do a one pas WTG shave in that 3 to 5 minute time frame if you are proficient with a straight razor. Still, if I had to do a quick shave including getting the razor ready, lathering up and doing a one pass shave the DE and brushless cream would still be what I would try. That eliminates the stropping and making lather with a brush. Oth if you start with the face lathered it is probably a tie between a straight and a DE for time needed. Both are quick enough.
