Okay, then I guess we'll go ahead and leave the +20 on the page for now. If the community tell us it's unnecessary, we always can remove it.

I completely understand your point about repeating the XP info. If you look on the Themes page, you will see that the items in the first section all show duplicate level information. San Francisco Theme even uses the same level info and the same XP info for both gems and materials, and it duplicates both items in the table.

Before we started working on the Extensions project two years ago, our usual method for displaying a single item that had separate costs for gems and for materials was exactly as you describe. Any information that was the same for both was displayed only once.

The result was mass confusion, and for many different reasons. The most important of these reasons was the inconsistent manner in which these items were displayed. For example, a dual-cost item could have: Making matters even worse, we often had two, three, or even all four of these formats in the same table. Experienced users usually could figure out what was happening. New users constantly asked questions about those tables. Frequently, they were still confused after someone answered their questions.
 * the same level info for both, but different XP info
 * different level info, but the same XP info for both
 * the same level info for both, and the same XP info for both
 * different level info, and different XP info

While working on the Extensions project, two of the experienced editors on the project mentioned that even THEY found the displays confusing. That's when we knew we had to find a way to make everything clear, every time.

We experimented with many different methods to display the information. In the end, there was only one method that every userincluding those new to the game itself always understood, without hesitation. That method is what you see on the Fifth Station page. ;-)
