GCD on Macros?

[Saccharin]

For this instance I simply have a weapon skill followed by a jump, just something that looks cool. I'm currently toying around with macros to figure out the extent of the customizability.
The macro itself is:
/ac "full thrust"
/wait 1
/gaction jump
If you hit it early the jump goes off. Its really not an issue, but I'm just wondering what Macros are capable of.

It's intentional so that you can't make a 'one shot' macro. SE dont want to make macros needed for best throughput.
