What Time Interval for Guest Posts?

For guest blog posts on higher DA blogs, what is too many too fast? I’ve been doing a lot of organic blog outreach and have a decent list of opportunities, but don’t want it to look bad for Google by suddenly piling them on. Would 1-2 per week be too much? Also, does it change the analysis if I’m looking to backlink these to an internal location pages / internal location service page instead of the main website?
