Hi Rajaram,
Thanks a lot for asking this question.
It is unfortunately not a possibility to generate a report for that score (or any score from the scorecards). That could be a great feature request you can ask on the community.
As for what the score means :
Elasticity Score: Measures how well you are turning resources on and off in response to changes in demand.
So in simple term, we measure the usage of instances vs the time they are used and the demand at that particular time. So are you shutting things down during the weekend / night when there is a lower usage or night.
If you are using AWS, you can create a nice chart with the following parameters :
