Simplified:  %CSP.Page is a collection of methods and event handlers without any own properties.
Related data are kept outside in %CSP.Request and %CSP.response.
But you may mimic InitialExpressions by using PARAMETERS 

I've been offering my reports on reviews for more than four years now,
as a personal service to the DC community, to show recent reviews.
And this covers any new review I can detect, not just add-ons to my own 700+ positive reviews
I started it long before the quality reports you mention were even proposed and implemented.

And even at my advanced age, I'm not willing to leave my audience in the lurch
until I'm explicitly forced by DC+OEX managers with a reasonable explanation.

In addition, the quality reports you address have neither a selectable overview
nor any kind of summary or view of progress. 

DSW definitely offers a strong improvement in graphics.
THOUGH you require some externally installed tools/libraries.

My intention here was to make it IRIS-only and all internal,
concentrating on the actions behind the scene. (query, tables, cubes) 
The charts are more eye-catcher for the visualization
