Solved?

strutting:

Tumblarity seems to be calculated for a recent period, maybe something even more reblogged that you did just expired. Chill, cousin.

delgrosso:

I posted seven times today.

Original text posts, original photos, a couple of reblogs, and even an audio post.

One of my posts was reblogged eleven times and was “liked” 53 times.

And yet my so-called “Tumblarity” has plummedted by 138 points since this morning.

I really don’t care, but at the same time I am fascinated with your calculations. Please go up to the chalkboard and show me how you arrived at that result. Be specific, and show your work. Here’s the chalk.

I think Jay is correct. When I noticed the huge drop in my score, my first-ever post (which got a lot of attention) had just turned a week old. Further confusing matters, Tumblarity had appeared midway through that week, so no one could tell what the starting point was.

The recency bias means they’re still not rewarding quite the right thing, but it’s less awful than I thought. I shall commence to chill.

But don’t go on vacation for more than seven days unless you’re OK with total Tumbscurity.

Hmm. Anybody got some bunny photos I can borrow?
