Before I suggest, can you confirm what does your FY look like? Is it June to May?
The example that you gave.
Therefore say that date was February 2018 I'd need to see June 2018 until today (Jan 2019) and that "performance" would be based on June 2017 vs. June 2018 and then for Jan 2019 vs. Jan 2018.
Please check the dates that are underlined. Just want to be sure there is no typo.
