Thanks for the kind words. I'm really starting to feel like I'm a dinosaur, nobody builds links like this anymore. So now there's me and apparently.....you :).
Nah, lots of us around. We just choose not to advertise :) We run a whole crew doing the same thing.
In answer to your question in my opinion, the type of link - intent of the link and source weigh heavily on how long the link takes to count, and the threshold of how many of those links you build in a short period of time to the website.
Other signals are likely taken into effect, such as brand factors and perhaps some social media in determining rate.
An up-and-coming brand that develop lots of positive signals in social media, strong advertising, lots of searches for brand name in Google.com can handle more inbound links in a relatively short period of time than a website with less positive signals in my experience
