Please explain how a ground probe 'can't' help trip a circuit faster than without one ....

Not saying it wont trip faster, but the fact is the ground probe will provide a path for current to flow which may not have been there before. Potential causing a problem. Personally I think if you have current flowing in the tank you should fix it ASAP and not provide a path for it.
GFI's are set to trip with 5mA difference between the lines. You might feel a slight poke but its not going to drop you to the floor before it trips. I cant see it changing the reaction time to a point it would be noticed.
IMO I think the ground probe can be ok if used correctly and you fix problems that arise. That being said, 9/10 times it makes us lazy in actually looking for the problem. So a $10 ground probe and 5 min to install problem "gone" or spend 20-30min tracing out which device is causing the leak and replacing something at a cost of 50? 100? 200? or more...your going to take the 10$ option every time and not truly fix the problem.
I wont ever use a ground probe I would rather check my devices, use drip loops and isolate myself through the use of a mat or dry towel. Be safe and smart. Just take the time to check each device and replace it its going to save a lot more in the long run.
