Not sure about crossing over tours yet. That would be a rather hefty load. There may be some things that can be done, but it will depend on how it impacts the server load.
The Squad and Country individual stats are next, then the comparative stats will follow.
Once the basic framework is flushed out, then they should all come fairly quickly. Went through some major restructuring today. Should be ready to show tomorrow.
Hopefully that will do it and we can move forward with the rest of the stats functionality.
