Want info icons on Benchmark page to to pop-up section definitions

On the Performance Benchmark page, there are two Sub-sections: 'Growth from Captial Gains' and 'Growth from New Capital'. I would like to see info icons (i in a circle) next to each to explain how you define each category and where you are getting the data, espcially the 'New Capital' section. I normally just pay attention to the Capital Gains to rank my performance, but find your inclusion of the New Capital figure boosts my performance figure (pleasingly), and gets me closer to my benchmark. I am just not sure how/why?
