Is the DPS/TDO Rankings working?

Yes. For TDO at least, it doesn't seem to work properly anyway: It doesn't take into account resistances against the enemy pokemon's attacks when calculating TDO, only the SE damage on its own side and weather.

I was about to post this thread as well since it's not working for me. I keep getting the Calculating box as well. I thought it was my internet until I tried it at two different locations.

Hi,

Thank you for bring this up. I've worked out a fix to address the issue. Please see if it has been resolved.

By the way, 9 of your Pokemon aren't imported correctly due to incorrect CP value basing on level and IVs.
