Show averages for three different types of results

I need to show the difference between three different types of servers for example.

CitrixServer TotalStartupTime OAIMFEP06 15.609 OAIMFEPV94 27.876 OAIMFEPT07 17446.984

Virtual servers have 'v' in the name, test servers have 't' in the name and physical servers have neither T or V in the name.

I would like to show the average TotalStartupTime for each type of server.

Thank you SplunkBase!

CitrixServer    TotalStartupTime
