Dude, I will make it more simpler,
In one particular test in the famed 'Arjun outgunning and outrunning T-90' trial there was a test in which the tank had to stop , very briefly, at a particular place, target and fire. Arjun could do it without stopping and hit the target with a better accuracy..
The crew of Arjun was not changed in a full day of tests but the crew of T-90 was changed twice because they got exhausted..
Its just not a Ferrari, its more like a sports car with the luxury of a sedan..
Its a wonderful tank, it could have been better if not for the politics, which should be removed from these organizations which are supposed to innovate (R&D and politics don't gel, at all!)
