Warp Stabilizer progress status

Question

Hi,
I need to get an alert when the stabilization process is complete.
So i try this :
i am reading the first three text labels on the effects panel :
During analysis:
the first label is empty
the second label display alternatively 
Time remaining : 41 seconds
or
64 % (frame 70 of 188)
the second label display :
Stabilization
During stabilization:
the first label is empty
the second label display
188 frames @ 0:00:21:18
and the third label display alternatively
Stabilization ..
(the number of dots and spaces varies)
When stabilization is complete :
the first label is empty
the second label display
188 frames @ 0:00:21:18
and the third label display
Stabilization
So i can read the label and deduce the process state.
// in a scheduled task
function checkStabProgress()
var effect = currentComp.layer(1).Effects.property(1);
var label = effect.property(1).name;
var label2 = effect.property(2).name;
var label3 = effect.property(3).name;
if(label == "" && label2 != "" && label3 == "Stabilization"){
     alert("Stab Complete");
It's seems to be a crappy way and sometimes an alert prompt before stabilization complete.
Is there a better way to do what i do ?
like event listener ? or something more clean and formal ?
thanks ++

Although it's easier (more convenient) to accomplish the mission in After Effects, you can do it in PrPro as well:
1. Nest your shaky footage.
2. Within the newly  created nested sequence apply Garbage Matte onto the footage to separate the woman on the foreground. E.g. draw Eight-Point Garbage Matte around the woman.
3. Create a Color Matte, pick e.g. R:7 G:7 B:9 to more or less match its colour to your footage background and drop this Color Matte above your footage with Garbage Matte.
4. Copy Garbage Matte from the footage and paste onto the Color Matte, delete or disable Garbage Matte on the footage. Optionally apply Fast Blur effect onto the Color Matte and dabble with Blurriness value so as to soften (feather) Matte's edges, adjusting Garbage Matte points if necessary.
5. Jump back to your master sequence and apply Warp Stabilizer onto the nested sequence, formerly your shaky footage. Set Stabilization to No Motion.
6. When done, switch to your nested sequence, disable the Color Matte eyeball, switch back to the master sequence, enjoy.
