Tag Comparison Between Servers

So I am at a monitoring center with it's own PI server which is sent data from another PI server.  What i plan on doing is having a visual where i can compare values at the same time stamp between each server. The plan is to view issues that may come in from something between servers.  I'm unsure if using trends "Buffers" the data, but the values that appear in a trend is different than a value that would come in a value box. Even if i use "GetTraceValue" to pull data into a list box, the values dont match the trend.  Is trend data buffered or smoothed in any way?  Also, is there a logical way to be able to compare data between servers which should always be exact, but to fill into a list box if they are not?
