Another aspect is that there is a large span in the amount of water you can let the rice absorb. A 1:1 ratio of water to rice (not accounting for evaporation) is all you need to cook rice no matter if it's short grain or long grain, but a lot of rice will also happily absorb more, like 2x its weight, if you give it enough water and time. It sounds like you are using long grain rice given the large cooking time and high water ratio.
