Compare values based on date filter

Apologies for a possibly dumb question and thanks in advance:

I require to create two tables based on the data both with indepedent date filters. So far, so good.

I need a third table however, that gives me the change in carrots and percentage dynamically based on the respective date filters of the two tables. For example:

Report 1:

Report 2:

How can I report 3 have dynamically calculate based on the respective filters so I can add it to my dashboard?

Report 3:

Thanks so much!
