I find that it makes upshifting easier
I attribute it to the high miles on my car but in the winter when the car is still fairly cold, within a few miles of hime still, it is dificult to get first gear and sometimes second. By letting the clutch out for a second in neutral it makes the shift easier.
This also maybe in part to the fact that the gears are used to oil the transmission. So if the gears are not turningthe trans isn't being oiled. - from my understanding
