Any compression numbers for Dirty Transparency over a larger image bank? And what about computing the average as the average of the individual compression ratios?

I mean, when computing the Average of the individual compression ratios on the actual image bank, the results are 35% vs 32% in favor of Dirty Transparency. So, the benefits are only 3% in this case (instead of 12%).

The significant difference in the average results depending on the average calculation method (12% vs 3%) comes from the fact that, with the method you used for computing the average, the bigger the file is, the bigger its impact on the overall average. And, since the larger file (by far) is the only one having a compression rate > 6% when compared to ‘No Dirty Tr’ (i.e. 43%-7%=36%), it has a big impact on the overall average…. However, when computing the average of the individual compression results, each file has the same weight in the average.

IMO, both methods for computing the average are good but they give different information… However, I was wondering what are the benefits of Dirty Transparency over a large image bank when using both average calculation methods.

Thanks.

@Kim: We have a private beta for our API that launched last weekend. Joost de Valk is helping me out by working on a WordPress plugin for the API. Let me know if you want access to the beta API, and I can set you up.
