Looking for some help to create a special type of measure/visualisation

[Anonymous]

Hi, everyone. I'm creating a weekly dashboard which means to show the results of all my company's managers in terms of performance (in %). One of the visualisations I wanna implement is something like a card which shows for how long the top 1 manager is leading the poll. Example: Manager A is leading the ranking for 22 days in a roll. The ranking will be updated 2 times a week (Tuesdays and Thursdays) and I would like some help to build this. I think I should use a special DAX Formula for this, but I don't know where to begin. 

Problem 2:

I'm also planning to show in a different visual a table with the results of the day in question and his variation compared to the last day in which the data was updated. Example: If today is 5th July (Tuesday), I wanna show the percentage performance of this day and compare with last week's thursday (28th June) showing the variation.

Hi, @Anonymous 

If the data source does not contain historical data, and the data is always updated dynamically, it is difficult to get how long the top 1 manager is leading the poll.

And if you want update the rank 2 times a week (Tuesdays and Thursdays), it is recommended to publish your reports to PowerBI service and configure scheduled refresh.
