SEO and Who is, advice needed.

I have my own network of really high authority sites. Over 50.
Now most domains are on different Class C ips, some times i have a few domains like 1-4 on the same ip. I have used these to rank for highly competitive keywords like "Country name SEO" and "Country name web design" where the country name is a medium sized country of more than 50 million people.

The thing is most of the Whois info is the same. How much could I be loosing in link juice for my whois honesty? I have an issue with lying even in whois info.

Does Whois info at my small scale make a difference, if not would it make a difference at 100 ro 200 domains?

If I like have a group of domains all in one godaddy account, and change who is for each, can google through its registrar info know that all these domains are on one nic handle? I use multiple registrars about 3 different ones, should I use more?

I have heard of others prior that own hundreds of domains to ask their host to split up their domains on different ip's and separate the servers for them for that very reason and also for adsense issues...

I have my domains on separate ips like 35 ips for 50 domains some in different data centers, some in different continents even.

BUT

Nearly all share whois with my name on the whois

My questions is mostly about the whois
