How many requests for fulls/partials should you get before you pause querying or should you never pause?
I currently have 3 fulls and 8 partials out. I feel relatively confident in my manuscript after about my 100th revision. But I do statistics for a day job, and I know that it's partially a numbers game, mostly subjective, and partially luck. So is there an etiquette to this? A general guideline? Just trying to figure out what is professional and respectful, while giving me the best possible chances. I appreciate any thoughts / advice you have.
This is the kind of advice where my opinion doesn't matter at all. As long as you've queried me, I'm fine. If you haven't queried me, you need to send at least one more.
That said, your question has merit. The people you should ask however, are writers. They're the ones who, armed with Excel spread sheets, industrial strength livers, and voodoo dolls in the shape of sharks, have more information (data points you statistical people call them) than I do.
My answer is simple: 100 queries at least.
And query till you just can't bear it anymore, then send one more (query #Gazillion +1)
Meanwhile, as you query, you're working on novel #2.
After you've sent Query #Gazillion +1, you'll start to query novel #2.
Query, lather, repeat.
I hear a lot of stories about people who found an agent only after a very long process. I hate to see you stop before you've gotten to QGazillion +1 because you think there's a magic number.
The comment column though is the place where you'll hear from the people in the trenches. Pay attention to what they say.
