early build tips

[Circuit]

There a little trick i stole from a 2000+ player ( i think is blackheart when i watch his replay)

Sometime when you begin the hydro is very close to the start point. here my build order

Acu: fac, 3 mex, move for building range for hydro
fact 2 first engie: hydro than split for expention
Acu: assit hydro

Normal build up for the map

I place my fact in a good range from the hydro and switch the side they come out to be sure to get the shorter path way. Here a exemple, the hydro of gap of rohan is very close from the start.

ok, but where is the trick?
i think on my streams in swear every almost game cause i always forget to switch rally point in time and my engies have to walk extra time...
when i saw game 1rst time in 2006, i was shocked and hyped about everything in it, and units that you can see being made in factories were looking so so cool, and already there i noticed that they change their orientation when you switch rally point, and if you switch rally point while unit is in construction, it usually tryes to turn inside of factory, and that is delaying factory from producing on tiny amount of time
