Perhaps this was just coincidence, but I also believe that for sites which 1) have reasonable pagerank/trustrank/etc and 2) that are updated frequently that the googlebot will visit more often. Your site clearly qualifies on both of those tests.
I’ve also seen brand new domains and brand new sites without any intrinsic rank make it into the index within days, and I believe there is some crawling/inclusion preference given to new domains to make sure the engine reflects the latest content.
And sometimes…it’s just not worth trying to predict what’s going on there
