List Of Server Merges

hi so far i know ...
1-48 made 130
65-80 made 131
600-603 made 133
49-64 + 81-92 made 134

what are the other merges ?

S600-s603 is now a133

S600 to s603 is s133

S604 to s607 is s135

S93-s96 become s132

General Question- what's the average age of a server before it merges?
Like I know some servers have merged multiple times.
For example is it:
First merge - 12 months
Second - additional 18 months
Third - even greater time

Or is greater time required between merges? Or are merges calculated off activeness of the remaining players? If so, do all accounts get included in this data collection (including alts) or the number of IP addresses logging into the server?

Would be interested in finding this out.
Thanks
Nat
