Adding to hits, and showing page visits

hello
I have tried almost all the statistical plugins for WordPress, but from my point of view, WordPress lacks a good statistics add-on. Of course this is a personal opinion, not a documented report. I have two questions about WP Slimstats:
1- How can I add to the number of visits or visitors? I have seen the option “add to hits” in other statistical plugins, but not in Slimstats. For example I want WP Slimstat to start from 15,000, not from zero, because I have already had 15k visits in the previous non-Wordpress CMS. What about adding to page-visits?

2- Is there a way I can show the number of page visits to my visitors? Something like this:
This page has been visited 2117 times by 400 visitors.

I thought these were the most obvious features, but none of WordPress statistical plugins had both of them together, or maybe I couldn’t find. Another problem was, almost all WordPress statistical plugins did not work correctly on Localhost (Wamp Server). Again, this might be a personal experience, not a rule of thumb.

Thank you
