Not quite applicable but in Florida they have “hard time”. In most cases when you get prison time you only have to do 75% of your sentence if you have good behavior, called gain time. Right now it’s about 10 days for every 30 you serve. however they can sentence you in a way where you have to do every day of your sentence. In most cases like this they give a sentence of so many years which includes some hard time, like 5 years with two years minimum. This way you don’t qualify for any gain time until you serve 2 years. That means you loose 240 days of gain time, which is a lot on a 5 year sentence.
