 Not sure this ticket is a good place for such discussion, but will try to
 answer your question hoping the answer will bring some clarifications.

 > But, are really those numbers real?

 This is the global aggregated data the WordPress project has, here:
 https://wordpress.org/about/stats/ (click on "View as table"). Some
 (larger) hosting companies also probably have (or can get) similar data,
 and may choose to release it. May be interesting to see how that compares
 to the global data, but don't think it would influence a decision much.

 > If you have WP 3.9 + PHP 5.6, that's a ''ghost'' site… and this should'b
 be counted.

 Yes, some sites that are on older WP versions are also running on older
 PHP versions. But other, (many more?) are on newer PHP too.

 The "maximum 5% of sites that will be on unsupported PHP version" doesn't
 mean that the WP project will "leave 5% of its users behind". It means
 that (judging from previous experience) when that number is reached,
 chances are most of the remaining sites will be upgraded to the minimum
 required PHP version by the cut-off date. Of course there will be some
 "unmovable" sites that are left behind. However the actual number of these
 unmovable sites on the cut-off date would probably be a lot less than 5%,
 more like under 1% as seen with previous PHP version bumps.
