I'm pretty sure that most people that know about steemworld use it as a handy app for tracking progress.
I rely on heavily for account information.
I had noticed the same issues by following the ups and downs of the curation weighted averages displayed on the app where the variance was +- 10+% within 24 hours?
Good to know @steemchiller is on the case to update the program.
It is a very valuable tool and ideally could be integrated into the new steemit front end whenever that gets done?
Steempeak has some useful data on the UI.
