Yes, you are right, may be I have wrongly used the word "intelligent".
I just want to say it is not fixed, as least the flash duration will
change according to different shutter speed, it is not a stupid flash

Yes, but the balance between ambient and object illumination is hard
to determine. I have once made a day shot into evening shot by using a
24/2 getting very close to the object.
