Still a hefty number. It is important to note that the User Survey lumps all versions of a given OS together, whereas the TC reference [2] only considers the latest LTS/stable version. If the User Survey split out latests LTS/stable versions vs. others (e.g. Ubuntu 16.04 LTS), I expect we'd see Ubuntu 18.04 LTS + Centos 7 adding up to much less than 78%.
