V3 is now live and brings the following additions:
Explicit check on banned hashtags. My system now explicitly tests if a hashtag is banned or limited in any way, so you can make informed choices. Limited or banned hashtags are tags where the top posts or recent posts are hidden or flagged by the community.
Power combos: data-backed combinations of hashtags that can help you reach more people. Power combos are hashtags that are found in correlation with the main hashtag and are often used in combination with the main hashtag. With a new scripted addition to the spreadsheet, you can now calculate the strength of the correlation and only include power combo's that are as strong as you want them to be. You can see an example in the OP.
