It makes no difference.
What you are doing is PAO system
But instead, you seem to Reverse the PAO to OAP
Captain Hook | getting eaten by | A Crocodile
This is a reverse PAO, meaning; you are applying Object Action Person.
You might as well have “Crock is eating Captain-Hook”, it would be much faster.
So really it’s the same order, Something is Doing Something To Something
Which makes no difference to PAO system, It can be OAP if its easier 
PAO is basically a Chain-Link system, 3 things are Chained together.
In your case, its OAP but in the reverse order 
You seem the make the person Wait, and then have the object apply the action to it after making him wait, hence it’s why it’s slowing you down.
You could probably do better if you see the Object first, apply the action to the Person, if that is easier for you.
I use a totally different approach then most people I know. That’s one of my reasons why I use the shaper system. I can’t get confused with it, and the actions are all ready to be used by itself and or with a person.
Let me give you an example that may help you to memorise faster. I had the same issue when using the persons, now I dont use them, but in the future I might because the actions are all ready for the persons to use instantly, I dont have to think.
I have also created and identified a good few (more than 10) Link Methods while I was working on this heavily, which increased my speed instantly.
In my system 00 is the Egg.
Now the egg itself has no life to it, it just stays there.
So when an Object has no life or anything special about it, I then use the “Give It A Life” Method.
So I imagine the Egg with Hands, arms, and legs.
Even now, there is nothing special about the egg, except it has arms and legs.
This is when I use “The Hero Powers” method.
In this case, I gave it the power of being able to “Stretch” his arms to any length.
So the permanent action has become, “The Egg’s Arms Stretching out to Grab & Cuddle” the next object regardless of what the next object could be, it makes no difference anymore, because as soon as I see the egg, I know that his arms are going the stretch & cuddle the next object.
you may ask, how does this work with Persons?
Here is How the PAO works with the shaper
01: Spiderman
00: Egg Cuddling
28: The Crocodile
01 00 28
Spiderman Cuddling The Crocodile
I have no other action as “cuddling”. Each is different.
I have every single image, and every single action for each 2 digits, and are all ready as OA. I practice them using “Object Action” only which is 4 digits at a time.
So when they all are mastered, then adding a person to the system would be so easy as explained above.
The reason I don’t use persons at the moment is because it’s not always faster to recognise the faces and the clothing of my persons. Basically I will do that when I feel I want to use them. But using the Objects Actions Paired Linking System helps to be much more creative, especially using the link -pairs I’ve identified, which makes the whole thing so much fun.
Lately I was able to memorise 70 digits in 1 minute with using the OA.
Hope this helps and gives you some more ideas to increase your speed.
