My two cents.
Go back beyond COVID for data. >3 years. As you know with the rapid increase in values, limited inventory, selling $40k above list, multiple offers, etc., can make deriving adjustments mind boggling.
The increase in value alone can make what needs to be adjusted, seem that no adjustment is needed, if that makes sense.
Also be wary of those end units, they can throw the data off also.
I like pulling the condo plats (in my area it gives the floor plan of each unit). It shows me what view it could have and the location within the building. I print that off, and then go to the MLS. I note every sale on that sheet.....and let then calculations begin.
