Vistor-Profile is meant to show a summary of all visits of a vistor.
That's great!

At this time, it may give a distorted and incomplete and with this false image of a visitor.
The reason for this is, it partly picks and shuffles data points to show

• only from last visit,
• or from first and last
• or from all

To solve this one should give a real summary by
showing

• all Referes (instead of only first and last)
• all Cities
• all IPs, (instead of only last one)
• all Providers , (instead of none)
• all Devices
• all Browsers
• all Monitor-Resolutions (instead of one)
• all ...

"all" does not mean one has to show lists with repeating words & numbers:
one can work with things like:

referer:
"4x direct entry"
"1x google"
or
"80% direct entry"
"20% google"
