Clarification on Comparing Campaign Performance Data for Partners

Hello Everyone, i got a quick question just to make sure we’re taking the right data output from the report attached below is a report that i’ve generated to look at a performance of a partner since we’ve launched a specifc campaign which is since 1st of sep. Its been around two weeks so i’ve divided the data using a formula to find teh average weekly appointments. What i’ve done here is that i’ve compared it to the previous month. Can i say that after launching the campaign there is a 11% increase in appointments of that partners compared to the same period last month ? My question here is related to the comparison feature so when comparing with previous month is it the same period last month or its calculated differently anyone’s help is highly appriciated
