A demo anyone can try: the real page with about two and a half years of made-up sessions at two invented card rooms. Logging, editing, deleting and exporting all work, and every change stays in the visitor's own browser. "Start over" brings the original sessions back.
The demo's sessions move forward to end yesterday, so every range from a week to all time has something to show whenever it's opened.
A 28-second video walks through the loop: log a session, read the line by dragging along it, switch ranges, compare the last session with the averages, and export it all to one file.
