I found the ratio of rice and water to be the main issue - and the rice cooker didn't fix that. I stumbled upon a recipe with a different approach that I use now.
Take plenty of water and get it to a boil. Add any amount of rice to the boiling water, and let it boil for 8 minutes. Then drain the water, remove the pot from the stove and put the lid on for a few minutes. Reduces the need for measuring quantities.
