How to know when rice is done? When it just starts sticking to the bottom of the pan.
...
When the water is totally absorb, rice is done. Some likes to let it sit for a few minutes, but that is not necessary.
Sorry, I'm sticking to my original scheme. (See what I did there?)
Rice sticking to the bottom of the pot isn't a bug, it's a feature: it's a very reliable indicator of when the rice is fully cooked and ready to eat. Works well for me, so I'm not going to change my method here.
One needs to be careful here and monitor the pot closely, as once it starts sticking, it will only stick more and more, to the point where one needs to scrape a lot of rice off the bottom of the pot. But believe me, this does work as a "done" indicator.
(Assuming, of course, that one puts the appropriate amount of water in. There we can find many schools of thought.)
