Retention

Hi, so I wanna know if this is normal. In one deck, I have a retention rate of 98.9% in the last month with a desired rate of 95%. On the other hand, I have another deck with a desired rate of 96% and a retention rate of 94%. The problem is that I've already finished that deck, and I'm just reviewing it again, so I think my retention rate should be higher. It's my first month with frs so idk if I'm doing something wrong. And thanks beforehand❤️
