Evidence that Macros Do NOT Cause GCD Delay or Lost Casts

[Mikoko_Miko]

Some spells such as Blizzard or Holy still have same cast time and recast time.

/macrolock
/crosshotbar copy BLM 2 BLM 3
/crosshotbar copy BLM 1 BLM 2
/crosshotbar copy BLM 3 BLM 1
/crosshotbar set Transpose 1 RAU
/macroicon Transpose action <wait.1>
/crosshotbar copy BLM 3 BLM 1

This is based on a macro I saw somewhere in Japan.

I identified the source of hotbar copy & set macros. It uses the same method as in the Macrology text.
【FF14】マクロでも先行入力を可能にする方法 (FF14 How to enable queue input using macros)
A macro in the video is like this. It was posted in 2015. It contains a removed action.

/micon "Fast Blade"
/ac "Fast Blade" <t>
/crosshotbar copy PLD 1 GLA 1
/crosshotbar set "Fast Blade" 1 RA3 <wait.1>
/crosshotbar set "Savage Blade" 1 RA3 <wait.3>
/crosshotbar copy GLA 1 PLD 1

This type of macro guarantees no GCD delay in exchange for additional presses. Unfortunately this method cannot be applied to many of my macros for GCD actions. I heavily use mouseover macros. These cannot be used without macros and pseuedo-queue is the only available option.

I found another video showing GCD delay.
【FF14】GCD遅延検証Ping40代とスキルマクロ(FF14 GCD Delay Inspection: 40ms range ping and macros)

It compares 4 cases side-by-side by repeated casting Jolt on a striking dummy. It was posted in 2023.
(1) average ping 41 normal action
(2) average ping 3 normal action
(3) average ping 3 single line macro
(4) average ping 3 repeated line macro
The video is paused at 0:07. Before the second cast (3) caused a delay. After an explanation, pause is canceled at 1:54. There are no significant delay other than in (3) after 50 casts.
