Not sure how you concluded the report is wrong
Sorry it was my mistake, I read the chart wrong with the lack of commas in one column I miscounted the digits on quick look at it.
There is nothing wrong with Cine, it is one of the newest tribes and hasn't had time to get it's Alexa ranking up, but I highly doubt it ever will unless it onboards new users as most users post on Cine without using the front end. STEM & LEO have a penalty for not using the front end which encourages people to use it. Cine does not. Doesn't mean anything is wrong with the distribution, just the front end isn't as actively use, but I a custom front end is being worked on. Not convinced that will change this fact though.
