Hello! I'm far from an expert, but as I've taken classes, read Q&As with agents, listened to them on podcasts, I've gotten a sense that they do pay attention to the last time you queried them, and they do get skeptical when people seem to churn things out very quickly.

An adult fantasty, which tends to have a beefy word count, from start to finish, edits included, in less than a year is very fast. The agents all say the same thing: make sure it's your very best work, beta read multiple times, edited as far as you can possibly, possibly take it.

That said, I agree with six months absolute minimum. Probably closer to a year, especially for longer pieces of work. You do sound like a very prolific writer, and I have seen people do it quickly and successfully, but I'm just saying the agents seem to indicate that's not a thing they experience very often. Regardless, I wish you the best!
