Their original target were lower, they raised it. Still not much of help, but still it is better. As for the 4 degree increase. I have not heard anything about a 4 degree increase. In COP26, several members said that 1.5 degree dream was alive, barely.

Realistcally speaking, 1.5 degrees would not be possible, it would be 2 or even 2.5 degrees, however, I dont think it would be such a drastic increase (4 degrees).

I agree with it being insufficient, however, seeing as how India updated and set a higher target right now, I am sure it will realize and set another higher target in the future.

Besides, your point wasn't about it being insufficient, your point was about it being uncompleted, which btw, would be much worse because something is still better than nothing.

If I remember correctly, India updated its goal in COP26 in Glasgow to 45% emissions.

Sources and media have also stated that India will not only achieve this goal by 2030 but overachieve it.

It is still not enough for the 1.5 degree mark sure, but India is improving its targets and will achieve it.

Edit: Secondly, how is emissions per capita irrelevant? India has to tend to its people's needs does it not? All of its people. You can definitely argue that its population is a problem, but saying emissions per capita is irrelevant is simply wrong
