Just Looking for Some Advice with At Home Insemination

My wife and I are trying for a baby. We have a sperm donor and have started trying this month. I’ve been reading about the chances of home insemination and know it’s about 1 in 5. Do the chances increase the more times you try? Let’s say, hypothetically, we try twice the day of the peak and once the following morning with fresh, not frozen donor sperm, would that increase the chances? By how much(or is there a way to know?)
