grandemange,
Drop Epic a note for their answer if you are concerned. They are really good to work with.
I usually lay the tape measure out next to the blank and put the guides on the table there too so I can see where they are going to be. If you are not familiar with the static deflection test, just google "fly rod static deflection" and read up. As Archfly mentioned. Epic blanks are well made and consistent so the guide placement should be good out of the box.
From a quick scan of the intertubes, the following page seems to have a good description of static deflection testing. It's from the US importer of Fuji guides.
http://anglersresource.net/StaticLoadTutorial.aspxIt takes some of the mystery out of guide placement. It isn't rocket science.
This reminds me that I have a 5pc epic that I have to wrap now that winter is setting in.
