After transitioning to SiteCatalyst 15, I noticed that Unspecified was removed from hierarchy reporting. This wouldn't have been the biggest deal, but I found that when you drilled down, the Total Hierarchy Views for the hierarchies above that level is lower than the actual total hierarchy views.
For example if I have 5 hierarchy views for item 1 on level 1, if i drill down to look at the level 2 hierarchy within item 1, if there were 2 views of items that had specification at level 1 but without specification at level 2, the total hierarchy views for item 1 would appear as 3 rather than the actual total hierarchy views to that item of 5.
