On few occasions i have had exhausted IMA battery (zero bar) due to severe traffic jam but I didnt quite notice whether the battery level drop dramatically within seconds, but I do notice the same thing whereby the battery will easily achieve full charge than normal driving conditions after moving away from the traffic jam.
I know there is a couple of discussion about this condition in the LYN Insight forum thread, perhaps you can get more details from the people there.
Thanks for the Info Bro

Yo man, you actually rev the engine to 3k RPM
and the car is stationary? How long did you rev the engine at 3K
Yes, it's a known thing . Not sure if its on the manual but as you read CR-Z forums and others. U would probably know that you can charge your IMA battery by revving it to 2-3k RPM. However, it's not recommended to do it frequently. Probably once in every month or even 3-4months.

while your stuck in jam.. is the car under stop start mode or is the engine running? if is at start stop .. u need to remember all electronics (AC/Radio/etc) will consume the IMA batt energy.. (base on my understanding
) and when you start to move back again is where the car re-charge its IMA batt which happens faster just like you said only at the last 2 bars takes a longer time.. (which is normal)
and for the advice that the SA gave to you.. i think most of us were advice the same.. even my self.. but i was told by my SA practice it once in 3-4 months.. and for me its not a good practice as you are putting stress on the cars engine..
revving at 3-4k just to run a recharge for the IMA.. but i did notice that.. you only need to rev at 3-4 just for the 1st 2-3bars only and the rest you can rev at 2-3k and it will still charge..
Thanks for the advice too
Yeap, I don't rev it frequently . This is the first time I'm doing it after 3 months actually.

One thing to note is that the IMA battery readout is not a real-time readout of the battery capacity. There will also be cases where slow drive or car park driving will deplete the IMA battery much faster, due to low rev ranges (IMA motor only helps at lower rev range to propel the car along). High speed runs actually charges the battery faster due to higher RPM on the stator magnets, thus you won't notice that the battery gets depleted. On the opposite end, the battery gets depleted at low rev ranges as the battery could not get charged back in time (low speed at the stator magnets), plus the constant use of the IMA motor to propel the car at low rev ranges.
For example, for my case, i will fully discharge the battery if I drive around Sunway Piramid's car park (just by searching 2 levels) and the auto-charge function will kick in whenever the car stops rolling (stationary). As long as there is no errors being displayed, the IMA is still functioning fine.
Second thing to note in case you are worried, is that the IMA fan have 2 speeds AFAIK, the high and the very high speed. The very high speed makes you think that there is a vacuum cleaner in your boot, but it disappears once the battery has been cooled down and re-charged.
Lastly, I do not see anywhere in the manual to ask us to fully recharge our IMA battery ourselves by revving the car to 3k rpm stationary, any idea if there's any reference materials besides the mechanic's "say-so"? I have never done it before, and don't plan to do it... it defeats the purpose of having a car if we have to constantly do this (hybrid some more, supposed to save the environment by reducing pollution). The main idea of the IMA is to re-cycle the kinetic energy which is normally lost during driving, thus improving fuel economy, but by revving the car stationary it sort of defeats that purpose. I would suggest instead that you enjoy your car every bit of the way... it is a really fun car to drive.
Thanks for the great info it, The reason why I actually rev it is because that it the battery actually dropped from 5 to 1 bar so it does makes me think that this is some kind of the problem where it was mentioned previously by some forum members which is knowledgeable in hybrid stating regarding the battery level of each batteries in the IMA. . Reading some articles or forums had mentioned that Honda's IMA uses 6-8 batteries (the ones that you use in torch light) and there are possibility where the battery level are not equal. One battery might have full batt level and another might have low batt level. Thats the reason why it appears on our display showing the battery has only 1 bar left but in fact there is actually battery inside. As the battery levels of each battery are not equal, it would sent a wrong signal showing the status of the battery is low and therefore, it would disable the use of electric motor although there are still battery left inside. Therefore, I thought of revving the engine (which is the 1st time i ever did after receiving the car 3 months ago) to charge the IMA battery fully hoping that it would balance all the charge level of the batteries inside the IMA. Not sure if it does work to balance the level of each battery but just wanted to give it a try....l'm not sure if you or anyone here could understand what I'm trying to explain though as the knowledge I have for Honda's IMA system is very minimal. Apologise for that though. Another thing I notice is that as you rev the engine to charge the IMA, it actually heats up? Because i can hear the vacuum cleaner sound in my boot which means its trying to cool down the battery. Anyways, thanks for the great info though.

tell me later 
So did you bang-bang back her car 
.. just gently use a microfiber cloth with a low sud soap and peform a zig zag formation while applying soap.. this is to avoid swirl marks...
